Finding distance and displacement from position-time graph

Google Classroom

Problem

A car rolls down a ramp in a parking garage. The horizontal position of the car in meters over time is shown below.
Graph of horizontal position x (in meters) on y axis and time (in seconds) on x axis. The initial position is -3 m at t=0 s, and the position increases linearly to 3 m at t=8 s. Then the position is constant at 3 m until t=16 s, then increases linearly to 9 m at t=24 s.
What is the displacement of the car between 8 s and 24 s?
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3/5
  • a simplified improper fraction, like 7/4
  • a mixed number, like 1 3/4
  • an exact decimal, like 0.75
  • a multiple of pi, like 12 pi or 2/3 pi
