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?
Answer & explanation
Correct answer: option 1
As , Speed is inversely proportional to Time
Ratio of A : B
Speed 3 : 5
Time 5 : 3
According to question ,
2R = 30 minutes
1R = 15 minutes
5R = 5 × 15 = 75 minutes
= 1 hour 15 minutes
So , Time taken by A to reach the destination is 1 hour 15 minutes .
