A)136

B)236

C)260

D)408

This is how I attempted to solve the problem. Can anyone point out where I went wrong

Lets say car A is the one 104 miles behind B.

34= B-104/4

AND THEN

25= B/4

Then I subtracted B-104 FROM B but i know this is wrong because these 2 equations produce different answers for B

Is there like a standard set up for these reactions?

btw Correct Answer is c)260
