Two trains start from a certain place on two parallel tracks in the same direction. The speed of the trains are 45 km/hr and 40 km/hr respectively. The distance between the two trains after 45 minutes will be
-
- 2 km 500 m
- 2 km 750 m
- 3 km 750 m
- 3 km 250 m
Correct Option: C
Relative speed = 45– 40 = 5 kmph
| ∴ Required distance = |  | 5 × |  | km | |
| 60 |
| = | km = 3 km 750 | |
| 4 |
