A train takes 15 seconds to cross a pole. If the speed of the train is 60 km/hr, then the length of the train is:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 250 m
To cross a pole, the train has to cover its own length.
Speed \(\displaystyle =60\times\frac{5}{18}=\frac{50}{3}\) m/s (1 km/hr = 5/18 m/s)
Length \(\displaystyle =\frac{50}{3}\times15=\) 250 m
