Question 1097977: Two boys on bicycles start cycling from the same place at the same time. One cyclist travels 15 miles per hour, the other travels 12 miles per hour, if they travel in the same direction, how many hours will it take before they are 9 miles apart?

You can put this solution on YOUR website! Let t be the time, in hours. Then:
15t-12t=9
3t=9
t=3 hours before they are 9 miles apart
