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:

walks 10 km

bus =x

train = 2(x+10)

so walks -70=60

60 - bus

60-x= 2(x +10)

60-x  =  2x+20

-3x = -60 +20

3x= 40

x = 40 /3

therefore the person traveled 40 /3 km in train

40/3= 13 + 1/3

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.✅
