Question

20. A man travelled one-third of his journey by train one-third by bus, one-fifth by car and the remaining 4 km on foot. What is the length of his total journey.​

Answer 1

Step-by-step explanation:

Let the total distance covered be x.

Distance covered by train = 1/3 x

Distance covered by bus = 1/3 x

Distance covered by car = 1/5 x

Distance covered on foot = 4km

A.T.Q.

1/3 x + 1/3 x + 1/5 x + 4 = x

13/15 x - x = -4

-2x / 15 = -4

2x/15 = 4

2x = 15×4

x = 60/2

x = 30 km

Hence, length of his total journey is 30 km.
