The ratio between the rates of walking of A and B is 2 : 3 and therefore A takes 10 minutes more than the time taken by B to reach the destination. If A had walked at double the speed, then in what time would he have covered that distance? |

Answer» Ratio of speeds = 2 : 3 ⇒ Ratio of times taken = 3 : 2 Given 3x – 2x = 10 ⇒ x = 10 ⇒A would have taken 30 minutes. But if A walks with double the speed, then he takes half the time, i.e., 15 minutes. |
