A train having a length of 360 m passes a post in 27 seconds. How long will it take to pass a platform having a length of 940 m?

OPtion

1) 96.00 sec
2) 97.50 sec
3) 97.00 sec
4) 98.50 sec
5) 96.50 sec
6) 95.21 sec
7) 96.12 sec
8) 99.50 sec
9) 98.20 sec
10) None of these

Solution

Time taken to cross post=length of train/speed of train
so speed of train=360/27 m/sec

time to cross platform= (length of train+length of platform) / speed of train
time = (360+940)/(360/27) = 97.5 sec
