Two trains, A and B, start from stations X and Y towards Y and X respectively. After passing each other, they take 4 hours 48 minutes and 3 hours 20 minutes to reach Y and X respectively. If train A is moving at 45 km/hr., then the speed of the train B is
-
- 60 km/hr
- 64.8 km/hr
- 54 km/hr
- 37.5 km/hr
Correct Option: C
Let speed of train A = x kmph
and speed of train B = y kmph
| ∴ | = | √ | ||
| y | t1 |
| ⇒ 5y = 45 × 6 ⇒ y = | = 54 kmph | |
| 5 |
