Passage I
Five bicycle riders traveled during the same 35 sec time interval along a 1 km segment of a straight path. Point P was located at one end of the segment. D, measured in meters, was a rider's distance along the path from Point P at time t. Measurement of D began simultaneously for all riders at t = 0 sec.
Figure 1 is a graph of D versus t for Riders 1 and 2. Figure 2 is a graph of D versus t for Riders 3, 4, and 5.
5. A student stated that, based on Figure 2, Rider 5 did not travel at all between t = 15 sec and t = 20 sec. Is the student's statement correct?
Your Answer is
Correct Answer is B
Explanation
Look at figure 2, when the abscissa time is 15-20, the ordinate corresponding to rider 5 does not change, indicating that rider 5 has not moved at this time, so it is yes
