Problema Solution

two trains travel toward each other from city a and city b which are 400 miles apart, and they are traveling at the rates of 110mph and 90 mph. they started at the same time and reach city c at the same time.

a)in how many hours the trains will reach to city c between city a and city b?

b) what distance did the faster train travel to reach to city c?

Answer provided by our tutors

a) Relative speed of the trains = (110 + 90) mph = 200 mph

The distance of 400 miles will be covered in 400/200 hours = 2 hours

So, they will reach city c in 2 hours

b) The faster train would have traveled a distance of 2hours * 110 mph = 220 miles to reach city c
