In a 200 m race, P beats Q by 35 m or 7 seconds. What is P's time over the course?
-
A.
36 seconds
-
B.
47 seconds
-
C.
40 seconds
-
D.
33 seconds
Correct Answer:
D. 33 seconds
Explanation:
In a 200-meter race, A finishes the course 35 meters ahead of B, which corresponds to a 7-second lead. This implies that B requires an additional 7 seconds to cover the remaining 35 meters. By dividing the distance of 35 meters by the 7 seconds it takes B to cover it, we determine B's speed is 5 meters per second. At this constant rate, B would take 40 seconds to complete the entire 200-meter course. Since A finished 7 seconds before B, A's total time is 33 seconds.
