Question

If the length of the train is $700$ m and length of the platform is $500$ m, find the time taken by the train moving at $54$ km/h to cross-platform?

• A. $75$ sec
• B. $80$ sec
• C. $85$ sec
• D. $90$ sec

Answer 1

Answer: (B)

$80$ sec

Total distance $D=$ Length of the train $+$ Length of the platform

$=700+500$

$=1200m$

Speed of the train $S=54kmph=54\times \frac{5}{18}=15m/sec$

$S=\frac{D}{T}$

$T=\frac{1200}{15}$

$T=80sec$

Hence time taken by the train moving at 54 kmph to cross platform is $80$ seconds.
