Refer to the time zone differences printed at the top of the map. The time zone for Dallas is marked ; the time zone for all of Norway is marked . This means that Oslo is  hours ahead of Dallas, so we need to adjust accordingly.

The flight took off when it was  in Oslo; if we subtract , then we find that it took off when it was  in Dallas. Now subtract this from :

Adjust by adding  to :

The flight took .

Refer to the time zone differences printed at the top of the map. The time zone for Washington, DC is marked ; the time zone for Paris, France is marked . This means that Paris is  hours ahead of Washington, so we need to adjust accordingly.

The flight departed from Washington when it was  in Washington, so we add  to this to get , the time it was in Paris. Now we can add :

Now adjust again by subtracting ; this means it was  in Paris when the flight arrived.

From Statement 1 alone, it can be seen that Donna's share of the vote was the smallest of the three. Therefore, Craig and Elly were the top two votegetters, and they will face each other in the runoff.

Statement 2 alone provides insufficient information; without knowing the total number of voters, the share of the vote won by Craig (or any other candidate) cannot be determined from the number of votes Craig won.

From the diagram, it can be seen that Candidates A and B will compete in the runoff. 

Assume both statements to be true. Since Xenia is not Candidate C, she will participate in the runoff. However, we do not know whether she is Candidate A or B. If she is Candidate B, then Yancey, who is not Candidate A, must be Candidate C, and Xenia will face Zane in the runoff. However, if Xenia is Candidate A, Yancey or Zane can be Candidate B. Therefore, while it can be determined that Xenia is in the runoff, her opponent cannot be determined with certainty.

In 2 hours, 1 student can paint 4 large signs or 12 small signs. Therefore, 3 students are required to paint the large signs () and 5 students are required to paint the small signs (). In total, 8 students are required.

In the first three hours, he travels 180 miles.

In the next two hours, he travels 144 miles.

for a total of 324 miles.

Divide by the total number of hours to obtain the average traveling speed.

Tom runs a 100m race in a certain amount of time.  If John runs the same race, he takes 2 seconds longer.  If John ran at 8m/s, how fast did Tom run?

Let denote the amount of time that it took Tom to run the race.  Then it took John seconds to run the same race going 8m/s.  At 8m/s, it takes 12.5 seconds to finish a 100m race.  This means it took Tom 10.5 seconds to finish.  Running 100m in 10.5 seconds is the same as

Jim arrived at the common destination in 70 minutes, or  hours. His average speed was 54 miles per hour, so their workplace is 

 miles away from Jim and Julia's home.

Julia traveled those 63 miles in 80 minutes, or  hours, so her average speed was

 ,

or, rounded, 47 miles per hour.

Andy traveled for 50 minutes, or  of one hour, at 45 miles per hour, so the office building is  miles from Andy and Donna's house. Donna traveled this distance for 45 minutes, or  of one hour, so her speed was:

 miles per hour.

Let  be the rate at which Kenny drove. Then Marie drove at a rate of  miles per hour. The two drove the same distance, so, since Kenny drove 70 minutes, or  hours, and Marie drove for 80 minutes, or  hours, we can use the formula  to set up the equation:

Since Kenny traveled at 48 miles per hour for  hours, the distance each drove is 

 miles.
