Question

Two runners start simultaneously from the same point on a circular track of length 217 m and run in the same direction. One runs at a constant speed of 5.50 m/s and the other at a constant speed of 6.00 m/s. When will the fast one lap the slower one? How far from the starting point will the slower one have run? How far from the starting point will the fast one have run?

Answer 1

Since the faster runner is .5m/s faster then the slower runner and the track is 217 m long, it will take 217/.5=434 seconds for the slow guy to get lapped by the fast guy. At this point the slow guy would have ran 434*5.5 meters and the fast guy would have run exactly 217 more than this.
