Q. In how many seconds does a 180m long train moving at 108kmph cross a platform of length 150 mtr?
Option
a) 11 second
b) 9 second
c) 8 second
d) 7 second
Read Solution (Total 5)
-
- 108 kmph = 108 *5/18 = 30 m/s
The train is travelling at 30 m/s and it has to cover a distance of 180 m + 150 m ( Its length + Train length) = 330 m
It will take a total of 330/ 30 = 11 seconds
Answer is 11 seconds - 11 years agoHelpfull: Yes(7) No(3)
- ANS:- 11 seconds....
using speed of train = (length od plt frm + length of train) / (time taken) - 9 years agoHelpfull: Yes(3) No(1)
- 330/(108*(5/18))=11 seconds (a)

- total d=330
Speed=108*(5/18)=30
t=330/30=11s - 6 years agoHelpfull: Yes(0) No(0)
