If a man reduces his speed to 2/3, he takes 1 hour more in walking a certain distance. The time (in hours) to cover the distance with his normal speed is :
-
- 2
- 1
- 3
- 1.5
Correct Option: A
Since man walks at 2/3 of usual speed, time taken will be 3/2 of usual time.
| ∴ | of usual time = usual time + 1 hour. | |
| 2 |
| ⇒ |  | − 1 |  | of usual time = 1 | |
| 2 |
⇒ usual time = 2 hours.
