Question

a man walks 10 km then travel A certain distance by train and then by bus as far as twice by the train if the whole journey is of 70 KM how far did he travel by train

Answer 1

man walks = 10km

let train distance be x

then the bus distance = 2x

2x+x+10=70

3x=70-10

3x = 60

x = 60/3

x = 20

Answer 2

distance travelled by vehicles is equals to 70 - 10 that is equal to 60 km
let the certain distance travelled by train be x
therefore 2 X + X is equals to 60 and hence the value of x comes out to be 20 km
