At a bus station, buses begin their route at 7:00 AM. The schedule for two of the buses is based on the time intervals listed here. Bus A has a long route and leaves the station every 50 minutes. Bus B has a short route and leaves the station every 20 minutes. When is the next time that Bus A and Bus B will leave the station at the same time?

Answer:This is a lowest common denominator problem, since it's asking for when do 25 and 35 minutes coincide. They have 5 as a common multiple, so if you divide by the LCM of each, and multiply the two, it's 175.Basically this means 5 trips of A coincide with 7 trips by B. 5*25=7*35. 175 minutes after 8 am is 10:55am.
