Question

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?

Answer 1

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.
