A bus leaves a station at 10am and averages 60 mph. Another bus, traveling at 75 mph, leaves the same station 30 mins later following the same route. What time does the second bus catch up with the first bus?

Question

I don't know how to work this out at all!

Answer 1

In 30 minutes, the first bus has gone 39 miles

The 2nd bus goes 15 mi/hr faster.

So, how long does it take to cover the extra 30 miles?

It's the same as if the 1st bus stopped 30 miles away, and the 2nd bus drove 15mph to meet it.
