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.
3. Based on Figure 2, how far did Rider 4 travel between t = 0 sec and t = 15 sec ?
Your Answer is
Correct Answer is A
Explanation
According to figure 2, the ordinate distance of rider 4 at 0sec is 600 m, and the ordinate distance at 15 sec is about 375 m, so 600-375=225 m
