Problema Solution

Two trains

Train A is traveling at 60m and passes the train station at 10:15 am, and Train B is traveling at 80m and passes the same station at 10:30 am.

At what time will train B catch up to train A?

Answer provided by our tutors

Given this,

 

When B passed the station, A was 15 minutes ahead. It that 15 minutes, A moved 10 miles ( 40 mph x (1/4 of hour)).

B is catching up at 60 - 40 = 20 mph.So, it's  1/2 hour, 30 minutes.

From 10:30 AM, add 30 minutes. which is 11:00 AM.
