kevin started running the first week in januray. He ran 4 miles 3 days a week.

Greg strated running the secong week of january. He ran 3 miles 5 times a week.

By the end of what week had they run the same distance?
:
Let w = the week that Kevin will have run the same distance as Greg
then
(w-1) = the week that Greg runs the same as Kevin
:
(3*5)(w-1) = (4*3)w
15(w-1) = 12w
15w - 15 = 12w
15w - 12w = 15
3w = 15
w =
w = 5 weeks, they will run the same distance

Check by finding the actual distances
15(4) = 60 mi
12(5) = 60 mi
