Please help I really need to get this question right! Bus A and Bus B leave the bus depot at 4 pm.
Bus A takes 15 minutes to complete its route once and bus B takes 35 minutes to complete its
route once.
If both buses continue to repeat their route, at what time will they be back at the bus depot
together?
Assume the buses have no breaks in between routes.
Give your answer as a 12-hour clock time.
