Question

a man walk 10m then travel a certain distance by train and then by as far as twice by the train if the whole journey is of 20km how far did he travel by train​

Answer 1

Answer:

here is your name

Step-by-step explanation:

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
