Scott drove to his friends house and back.on the trip there he drove 72km/h and on the return trip he went 60 km/h. How long did the trip there take if the return trip took six hours?
60 km/h which took 6 hours 60X6=360 km were driven. Divide 360km by 72h would take 5 hours. So, it would take 5 hours to drive the same distance at 72km/h.
