When Michael catches up with Kevin, both boys will have run the same distance. Let this distance be d.
They will also have been running for the same amount of time. Let this time (in hours) be t.
Remember to add on Kevin's head start of 3 miles.
Hence, 7 t = 5.5 t + 3 (since speed × time = distance travelled)
1.5 t = 3
t = 2
Ans; 2 hours
