Question 1 of 15
1. Question
Two boats A and B start towards each other from two places A and B 112 km apart. The speeds of boat A and B in still water are 13 kmph and 15 kmph respectively. If A proceeds downstream and B upstream, after how much time will they meet?
Correct
Let the speed of the stream be x kmph and both the boats meet after y hours.
According to the question,
(13 + x)y + (15 – x)y = 112
or, 13y + xy + 15y – xy = 112
or, 28y = 112
or, y = 4 hours
Incorrect
