Adam can run a lap on a certain circular track in 50 seconds. Grampy Sampy can run a lap on this
track in 90 seconds. They start at the same location at the same time and move in the same
direction. If they each run at a constant speed, how many seconds will it take before Adam is next
even with Grampy Sampy? If your answer is not a whole number, give it as a decimal.
