One athlete won a 100-meter race with a time of 9.69 seconds.
Another athlete won a previous 100-meter race in 15.0 seconds.
If they ran in the same race repeating their respective times, by how many
meters would the faster athlete win?
:
Find the speed of the second runner
100%2F15 = 62%2F3 meter/sec
:
Find how far he would run 9.69 seconds
9.69 * 6.667 = 64.6 meters
:
100 - 64.6 = 35.4 meters behind the 1st runner when he cross the finish line
