Track: Sprinter A runs 100 meters in 15 seconds, while sprinter B starts 1.5 seconds later and runs 100 meters in 14 seconds.
If each of them runs at a constant rate, who is further in 10 seconds after the start of the race? explain
:
Find A's speed in m/sec: 100/15 = 6 m/sec
Find B's speed, 100/14 = 7 m/sec
:
Find A's dist after 10 sec; 10 * 6 = 66.67 meters
B started 1.5 sec after A, therefore
B's dist after 8.5 sec: 8.5 * 7 = 60.71 meters
