the answer is 480 units. You take the difference between the two numbers. I.E. 240- (-240)=480. When it comes to this situation think one person went 240 feet away and the other went 240 away. Neither of them are at the starting point so the answer can not be 0.
Took the test and the answer is 480 units, hope I helped...not really, I just knew the answer from the reveiw and seen this open and needed the coins so dueces homies
