Question
There are two trains A and B. A start from point
X at 8 AM towards point Y. Another train B starts at 9 AM from point X. If they meet at 12 PM and speed of A is 33 km/hr, while that of B is 22 km/hr. Find distance between X and Y.Solution
Speed of train A = 33 kmph
Speed of train B = 22 kmph
Time taken by train A to meet train B at 12 PM = 4 hrs
Time taken by train B to meet train A at 12 PM = 3 hrs
Distance travelled by train A = 4 × 33 = 132 km
Distance travelled by train B = 3 × 22 = 66 km
Therefore, total distance between X and Y = 132 + 66 = 198 km
