Question
There are two trains A and B. A start from point X at 5
AM towards point Y. Another train B starts at 7 AM from point X. If they meet at 9 AM and speed of A is 22 km/hr, while that of B is 30 km/hr. Find distance between X and Y.Solution
Speed of train A = 22 kmph Speed of train B = 30 kmph Time taken by train A to meet train B at 9 AM = 4 hrs Time taken by train B to meet train A at 9 AM = 2 hrs Distance travelled by train A = 4 × 22 = 88 km Distance travelled by train B = 2 × 30 = 60 km Therefore, total distance between X and Y = 88 + 60 = 148 km
