Question

Two trains started at the same time from two towns 750km apart and travelled towards each other. The slower train speed was 60km/hr. The faster train at 90km/hr. After how many hours will they pass each other

Answer 1

Hey there .... here's the answer to your question.....

The distance b/w the towns A & B is 750 km.....
let both the trains meet at distance of x km from town A......
let the slower train start its journey from town A ......... (you can take it the other way round)
For slower train........... 
Speed = 60 km/h
distance = x km
:. time taken = x/60
for faster train from town B ..............
Speed = 90 km/h
distance = 750-x km
:. time = (750-x)/90

THE TIME TAKEN BY BOTH THE TRAINS TO MEET EACH OTHER WILL BE THE SAME..

x/60 = (750-x)/90 => x = 300 km
time taken by slower train = time taken by faster train = x/60= 300/60 = 

5 hours (ans.)

hope it helps..........

Answer 2

Answer:

i,e., 60 X + 90 X = 750

150 X = 750

= x= 5

Step-by-step explanation: thus, the trains met after 5 hours
