Answer:

The man traveled 20km by train.

Step-by-step explanation:

If x is the distance he traveled by train, you can write this equation to represent the situation:

$10+x+2x=70$

Then, you can simply solve for x:

$10+3x=70\\3x=60\\x=20$

The man traveled 20km by train.

$10+(20)+2(20)=70\\10+20+40=70\\70=70$
