How many laps will each boy have run?

Question

 Josh, who runs at a rate of 3 laps per minute, had completed 2 laps already when he was joined on the track by Marshall. Marshalls pace is 4 laps per minute. At some point, the two will have run the same distance. 

Answer 1

Given:  Josh ran 2 laps
           Josh’s rate :     3 laps per minute
           Marshall’s rate: 4 laps per minute


                              Josh                   Marshall
First minute :        2 + 3 = 5                   4
Second minute:     3 + 5 = 8              4 + 4 = 8

Hence, they both have run 8 laps when they meet
