Reid and Tanner are racing to see who can get his community service hours for scouting completed first. Reid, who has already completed 20 hours, plans to volunteer for 10 hours per week going forward. Tanner hasn't started yet, but plans to dedicate 15 hours per week to his volunteer project from now on. Before too long, the boys will be tied, with the same number of volunteer hours. How long will that take?
