Question

A man walks 10 km, then travels a certain distance by train and then by bus as far as twice
by the train. If the whole journey is of 70km, how far did he travel by train?
​

Answer 1

Answer:

The man travels by train and bus distance = 70 - 10 = 60 kms. This distance of 60 kms is travelled in the ratio 1 : 2 by train and bus respectively. hence distance travelled by train = (1/3) × 60= 20 km ...so the distance travelled by train is 20 km and the distance travelled by bis is 40 km

please mark me as brainiest please....

Answer 2

Given :

A man walks 10 km, then travels a certain distance by train and then by bus as far as twice by the train.

To Find :

If the whole journey is of 70km, how far did he travel by train?

Solution:

Distance traveled by man initially = 10 km

Let x be the distance traveled by train = x

We are given that man traveled as far as twice by the train.

Distance traveled by train = 2x

Distance of whole journey = 70 km

So, 10+x+2x=70

10+3x=70

3x=60

x=20

Distance traveled by train = 2x=2(20)=40 km

Hence He traveled 40 km  by train.✅
