Question 118454
Powell is the world's fastest man. In the 100 meters, he currently broke the world record by a time of 9.74 seconds, I run the 100 meter sprint in 10.9 seconds. If we race, and we take off at the same time, what would be the distance between me and him, when he crosses the finish line.
:
All you have to find out is, how far can you travel in 9.74 sec at the speed of 10.9 sec for 100 meters.
:
Find your speed in meters per seconds (speed = distance/time):
{{{100/10.9)}}} =  9.1743 meters/sec
:
In 9.74 seconds
9.74 * 9.1743 = 89.3578 meters
:
Powell is at 100 meter at that time, therefore
100 - 89.3578 = 10.6422 meters behind him.
