Question

A TRAIN TRAVELLING AT 80KMH​-1 ​CAN REACH A
STATION X FROM Y IN 4 HOURS IF ITS SPEED IS ONLY 60
KMH​-1 ​ HOW MUCH TIME WILL IT TAKE TO REACH
FROM X AND Y

Dear student,
Here is the solution of your asked query:
Suppose the distance between X and Y is x km
Speed=80 km/hSo, time taken=distancespeed=x80And, x80=4               {As it is being given that time taken to reach station X from Y is 4 hours}⇒x=80×4=320kmNow, when speed = 60km/hThen, time taken =32060=163km/hTherefore, time taken to reach station X from Y=163km/h
