Question

The figure shows the graph of the distance covered by a particle in meters, versus the time elapsed in minutes:  True or False: The particle's velocity is negative for more than one minute.

Quizplus · Accepted Answer

Since the distance covered is decreasing from 0 to 1 minute, and then again from 3 to 4 minutes, the velocity (which is the rate of change of distance with respect to time) is negative during those intervals. Therefore, the particle's velocity is negative for more than one minute.
