Marks: +1, -0

A man covered a certain distance by a train at the speed of 40 km/hr and covers the same distance back by walking at the speed of 8 km/hr. If the whole journey took 12 hours, then what is the one side distance (in km)?

Validate

Solution:

Let total distance covered (both sides) = 2d km
Speed of train = 40 km/hr and walking speed = 8 km/hr
Using, time = distance/speed
⇒

d/40 + d/8 = 12

⇒

6d/40 =12

⇒

d=12×40/6=80
