Answer:
15 minutes
Explanation:
Given:
Speed of a train ( Train A ) = 112 miles per hour.
Speed of another train ( Train B ) = 80 miles per hour.
Question asked:
Traveling at this rate, how long would it take to catch up with another train
( Train B ) 8 miles ahead of Train A.
Solution:
By using :

As Train B is 8 miles ahead of Train A means :-
Distance traveled by Train A - Distance traveled by Train B = 8

By dividing both side by 32,


Now, converting it into minutes,
1 hour = 60 minutes
=

Hence, it will take 15 minutes to catch up with train B which is running 8 miles ahead of train A.
