Correct Answer: 54 km/h


Solution : Given: The distance of the train is 240 m and it takes 16 seconds to cross the telegraph post.
We know that, $\text{Speed}=\frac{\text{Distance}}{\text{Time}}$.
To convert m/s into km/h, multiply with $\frac{18}{5}$, we get,
So, the train speed is given as, $\frac{240}{16}$ m/s.
$=\frac{240}{16}\times\frac{18}{5}=54$ km/h
Hence, the correct answer is 54 km/h.
