Allen starts from X, goes to Y. At the same time Bob starts from Y and goes towards X. Once Allen reaches Y he changes his direction and returns to X. Once Bob reaches X, he changes his direction and returns to Y. Throughout Allen travels at 54 kmph and Bob travels at 78kmph. By the time they meet for the second time, Bob covers 48 km more than Allen. Find the distance between X and Y.
Correct answer: E
Explanation
Total distance 126km
in an hour both Allen and Bob covered 126km
that is 54+78=132
they meet for the first time Bob covered more KM than Allen. 78-54=24.
so when they meet for the second time Bob covered 24*2= 48 more km (ANSWER E)
