A boy covers a distance of 20 km in 2/5 hours, partly on foot at the rate of 5 km per hr and partly on bicycle at the rate of 10km per hour. Find the distance covered on foot?

Answer»

Let TIME taken to travel on foot = X
Then, time taken to travel on bicycle = (2.5 - x)

So,
5(x) + 10(2.5 - x) = 20
Solving, we get
x = 1

So, distance TRAVELLED on foot = 5 km

Hence, the boy covered 5 km on foot.

Hope this helps! :P
