Question

Ram goes to school by bus and cover the distance of 5 kilometre and come from school . going speed and coming speed are 5 km per hour how much total time he will take​

Answer 1

Answer:

Lets assume the distance from Ram’s house to the school be X.

When Ram travels at 5 kmph he takes X/5 hours to reach his school.

When Ram travels at 4 kmph he takes X/4 hours to reach his school.

We know that the difference between the time taken with the first case (5 kmph) and the second case (4 kmph) is 10 minutes (5 minutes early v/s 5 minutes late).

10 minutes is 1/6 th of an hour.

Therefore, X/4 - X/5 = 1/6.

This can be rewritten as :

X/20 = 1/6 or X = 20/6 = 3.33 km.

Therefore the distance from Ram’s house to his school is 10/3 or 3.33 km.
