A) 75 m
B) 125 m
C) 150 m
D) \[\frac{625}{3}\,m\]
Correct Answer: A
Solution :
Let x be the length of faster train. \[\because \] \[\text{Time=}\frac{\text{Distance}}{\text{Speed}}\] \[\therefore \] \[\frac{15}{3600}=\frac{x}{50-32}\] \[\Rightarrow \] \[x=\frac{15\times 18}{3600}\] \[\Rightarrow \] \[x=\frac{3}{40}\,km=\frac{3}{40}\times 1000=75\,m\]You need to login to perform this action.
