Two runners are running around an oval. they start together and one takes 300 seconds to complete exactly one lap while the other takes 1050 seconds. how many laps would the faster runner make before they meet again at the starting point.

If you break up how many 300 go into 1050 it is about 3 1/2 laps so you just keep adding on untill they are both at numbers where both can meet so the faster runner would run about 3 1/2 more laps when they were both to meet at the starting line
