If it took t hours to travel to college then it took 7-t to return home.
The distance travelled is the same so 15t=6(7-t), 15t=42-6t, 21t=42, t=2 hours.
So travel to college took 2 hours and it took 5 hours to return home.

Devante went to the college traveling 15 mph and returned home traveling 6 mph. if the total trip took 7 hours, how long did devante travel at each speed?
