A thief is noticed by a policeman from a distance of 200m. The thief starts running and the policeman chases him. The thief and the policeman run at the rate of 10 km./hr and 11 km./hr respectively. What is the distance between them after 6 minutes ?
-
- 100 m
- 190 m
- 200 m
- 150 m
Correct Option: A
Relative speed of police
= 11 – 10 = 1 kmph
| = | m/sec | |
| 18 |
| ∴ Distance decreased in 6 minutes = | × 6 × 60 | |
| 18 |
= 100 m
∴ Distance remained between them = 200–100 = 100 m
