Question

A man walks 10km.then travel a certain distance by train and 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

Let the man travels by bus be x

and the man travels by train be 2x

So, according to the question if the man walks for 10km out of the total journey then it means the remaining journey is done by bus and train out of the total journey i.e 70km

Thus,

Journey by bus+Journey by train=Total journey done by bus and train

• x+2x=70−10
• 3x=60
• x=20
• 2x=40

So the distance traveled by train is 40km
