Displacement, Velocity, and Acceleration Practice Test

A cart moves in 1D; positive is to the right. It travels from $x=0,\text{m}$ to $x=5,\text{m}$, then back to $x=2,\text{m}$.

What is the cart’s total distance traveled?

A cart moves along a straight track; positive is to the right. Its position is recorded: at $t=0,\text{s}$, $x=0,\text{m}$; at $t=2,\text{s}$, $x=6,\text{m}$; at $t=5,\text{s}$, $x=3,\text{m}$. Assume the cart moves smoothly between these times.

What is the cart’s average velocity from $t=2,\text{s}$ to $t=5,\text{s}$?
