A train covers a distance between station A and station B in 45 minutes. If the speed of the train is reduced by 5 km/hr, then the same distance is covered in 48 minutes. The distance between station A and B is
-
- 60 km
- 64 km
- 80 km
- 55 km
Correct Option: A
Let the distance between stations be x km, then speed of train
| = | = (4x/3) kmph | |||||
| 60 | ||||||
| ∴ | = (48/60) | |||||
| − 5 | ||||||
| 3 | ||||||
| ⇒ | = | ||
| 4x − 15 | 5 |
⇒ 16x – 60 = 15x
⇒ x = 60 km
