Question

(Hint: Three consecutive multiples UI de ti
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:

let the man travel by bus be x

and the man travel by train be 2x

so according to the question if the man Walks for 10 km out of the total journey then it's means the remaining journey is done by bus and train out of toatal journey i.e is 70 km

thus,

Journey by bus +journey by train= total journey done by bus and train .

x+2x=70-10

3x=60

x=20

2x=20
