28.A train is moving at a speed of 132 km/hr. If the length of the train is
110 metres, how long will it take to cross a railway platform 165 metres long?
A. 7 sec
B. 8 sec
C. 8.5 sec
D. 7.5 sec
Option : D
Speed of train = | 132 x | 8 | m/sec = | 110 | m/sec. | ||
18 | 3 |
Distance covered in passing the platform = (110 + 165) m = 275 m.
Time taken = | 275 x | 3 | sec = | 15 | sec = 7 | 1 | sec. | ||
110 | 2 | 2 |
