Question
There are two trains A and B. A start from point
X at 4 AM towards point Y. Another train B starts at 6 AM from point X. If they meet at 8 AM and speed of A is 50 km/hr, while that of B is 60 km/hr. Find distance between X and Y.Solution
Speed of train A = 25 kmph
Speed of train B = 44 kmph
Time taken by train A to meet train B at 11 AM = 4 hrs
Time taken by train B to meet train A at 11 AM = 2 hrs
Distance travelled by train A = 4 × 25 = 100 km
Distance travelled by train B = 2 × 44 = 88 km
Therefore, total distance between X and Y = 100 + 88 = 188 km
