Question

A person walks from his house at a speed of 4 km per hour and reaches School 5 minutes late . if speed has been 5 kilometre per hour he would have reached 10 minutes earlier the distance of school from the house is?

Answer 1

Answer:

let the required distance be x

x/4 - x/5 =(5+10)/60

x/20 = 15/60

x/20 = 1/4

4x=20

x=20/4

x=5

so the distance is 5 km
