A bus leaves a station at 8:00 am and averages 30 mi/h. Another bus leaves the same station following the same route two hours after the first and averages 50 mi/h. When will the second bus catch up with the first bus?

in the two hours between the buses, the first bus has traveled 60 miles.

So, the other bus must make up 60 miles at 50 mi/hr, which will take 60/50 hours.

Add that time to the bus's departure time.
