reaches B, then travels back till he meets Joe. What is the fraction of the distance AB that Joe has travelled?

Suppose Joe went J feet. Moe went x times as far, or xJ feet. But Moe & Joe combined went 2B feet, where B is the distance between A and B. So (1 + x)J = 2B. But we want the fraction J/B, which is 2/(1 + x).

Nor do you need to know any of those things since the question asks for a fraction of the distance AB that Joe has travelled when he meets Moe on his way back.
Example: If Moe walks 3 times as fast as Joe, he will travel 3/2 of the distance AB while Joe travels 1/2 the distance and he'll meet Joe as Joe gets halfway to B.
C'mon Dewd. It's a simple ratio and proportion problem.

un answerable math problem.... you dont know distance between a and b, how fast either person is walking, or the time that each person traveled.....
