Finding distance and displacement from graphs

Problem

A baby elephant trots in a straight line along a river. The horizontal position of the elephant in meters over time is shown below.
Graph of horizontal position (in meters) on the y-axis and time (in seconds) on the x-axis. The graph shows that the elephant travels in three straight-line segments between times t, equals, 0, start text, space, s, end text and t, equals, 24, start text, space, s, end text.
The elephant stays stationary at 6, start text, m, end text from t, equals, 0, start text, s, end text to t, equals, 8, start text, s, end text. The elephant moves to 15, start text, m, end text at t, equals, 16, start text, s, end text, and then moves to 0, start text, m, end text at t, equals, 24, start text, s, end text.
What is the displacement of the elephant between 0, start text, s, end text and 16, start text, space, s, end text?
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3, slash, 5
  • a simplified improper fraction, like 7, slash, 4
  • a mixed number, like 1, space, 3, slash, 4
  • an exact decimal, like 0, point, 75
  • a multiple of pi, like 12, space, start text, p, i, end text or 2, slash, 3, space, start text, p, i, end text
start text, m, end text
