Question 1163670: A and B start running from the same point and along the same direction on a circular track with 300 meters. A runs 5 meters per second and B runs 4.4 meters per second. When they meet the first time, how far in meters is it from the starting point?
Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! A will do one more lap than B or 300 m more (assuming the circumference is 300 m)
A is gaining 0.6 m per second on B and will catch up the 300 m in 500 seconds, 300/0.6
In 500 seconds, A runs 2500 m and B runs 2200 m
divide each of these by 300 m, and the remainder for both is 100m, and that is how far from the starting point A will catch B.
