Example Question #31 : Word Problems
Six friends work for a company as maintenance staff.
Above are six graphs. Each graph shows the distance that one of the six is from his home from 8 AM to 9 AM on a particular day, relative to the time. The time of day is represented by the horizontal axis, and the distance from home is represented by the vertical axis. The name of the person represented by each graph is under the graph.
Of the six, who got halfway there, got sick, and returned home?
Mr. Cleese
Mr. Palin
Mr. Chapman
Mr. Gilliam
Mr. Gilliam
The person's distance increased as he drove to work, but decreased as he returned home. This describes the graph for Mr. Gilliam.
Example Question #32 : Word Problems
Six friends work for a company as maintenance staff.
Above are six graphs. Each graph shows the distance that one of the six is from his home from 8 AM to 9 AM on a particular day, relative to the time. The time of day is represented by the horizontal axis, and the distance from home is represented by the vertical axis. The name of the person represented by each graph is under the graph.
Of the six, who took the express train directly to work?
Mr. Palin
Mr. Cleese
Mr. Jones
Mr. Chapman
Mr. Cleese
The distance from home of the worker in question would have increased steadily without any interruption. The graph with the constantly increasing line is the one to choose; this graph belongs to Mr. Cleese.
Example Question #33 : Word Problems
Six friends work for a company as maintenance staff.
Above are six graphs. Each graph shows the distance that one of the six is from his home from 8 AM to 9 AM on a particular day, relative to the time. The time of day is represented by the horizontal axis, and the distance from home is represented by the vertical axis. The name of the person represented by each graph is under the graph.
Of the six, which one called in sick at 7:30 AM and stayed in bed?
Mr. Palin
Mr. Jones
Mr. Cleese
Mr. Gilliam
Mr. Jones
Someone who called in sick would remain at constant zero distance from his home during the entire time. This would be represented by a horizontal line along the zero axis; this describes the graph for Mr. Jones.
Example Question #34 : Word Problems
On a map, one half of an inch represents forty miles of real distance.
It takes John 90 minutes to get from Kingsbury to Willoughby driving an average of miles per hour. How many inches apart, in terms of , are the two cities on the map?
The distance in real miles between Kingsbury in Willoughby can be found by multiplying rate miles per hour by time 90 minutes, or one and a half hours:
Let represent map distance between the cities, One half of an inch represents forty miles of real distance, so one inch represents twice this, ir eighty miles. The ratio that compares map distance and real distance is
Example Question #474 : Problem Solving
On a map, one half of an inch represents thirty miles of real distance.
The towns of Waterbury and Nashua are three and one half inches apart on this map. How long, in hours, would it take for someone to drive from Waterbury to Nashua if his speed averaged miles per hour?
On a map, one half of an inch represents thirty miles of real distance, so one inch represents twice this, or sixty miles. The actual distance from Waterbury to Nashua, which is three and a half inches on the map, is
Therefore, the two cities are 210 miles apart. Divide the distance by the rate to get the time:
, or .
Example Question #474 : Hspt Mathematics
John is driving to his parents house on the highway going 45 mph. If he travels for 6 hours, how long was the trip?
You will use the distance formula of,
.
Identify the rate and time that is given.
From here, substitute the known information into the formula to calculate distance.
First to find the ones digit multiply the ones digits together.
Carry the three to the tens digit. Now, to find the tens and hundreds digit, multiply six by four and then add in the three that was carried.
Placing these numbers in their appropriate places results in the following solution.
Example Question #34 : Word Problems
What is the prime factorization of 48?
We can find the prime factorization of a number by dividing 48 into smaller numbers.
2 is prime
2 is prime
2 is prime
Both 2 and 3 are prime.
So we have four 2's and one 3. Multiply these numbers to get 48.
Example Question #2 : How To Do Other Word Problems
What is the least common multiple of 6 and 8?
One easy way to find the least common multiple is to take the largest of the numbers given to you, and find its multiples.
8: 8, 16, 24, 32, 40, 48...
Now start with 8, and see if any of these numbers is divisible by 6. The first number that is divisible by 6 is the least common multiple of 6 and 8.
8: No
16: No
24: Yes
24 is the least common multiple of 6 and 8.
Example Question #35 : Word Problems
How many whole numbers are between and ?
Convert each fraction to a mixed number.
So how many whole numbers are between and ?
4, 5, 6, and 7 would fall between these two numbers. 3 would not. So there are 4 total whole numbers between them.
Example Question #36 : Word Problems
What is the next number in this progression?
18, 10, 2, -6
This is an arithmetic progression. Therefore you must add or subtract a number to the number before it to arrive at the next number. We must find the difference between each number and apply it to the final number to find the next number in the series.
To start, take the second number and subtract the first number.
In this case it yields
Then take the third number and subtract the second number which results in
If the resulting number is the same you now know the difference between each number in the sequence and can apply the difference to each resulting number.
In this case the difference is
So we take the final number and add the difference to it to result with
