The speeds of A and B are in the ratio 3: 5. A takes 30 minutes more than B to reach the destination. In how much time does A reach the destination?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e 1 hour 15 minutes
Given that
The ratio of the speed of A and B = 3: 5
The time ratio of A and B is reversed by the ratio of speed for constant distance = 5: 3
According to the question
5x - 3x = 30 minutes
2x = 30
x = 15 minutes
Hence, The time in which A reaches the destination = 5x = 5 × 15 = 75 minutes = 1 hour 15 minutes
