A train running at 54 km/hr takes 16 seconds to pass a tree. What is the length of the train?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 240 m
A tree is a point object, so to pass it the train covers only its own length. Change the speed to m/s by multiplying by \(\frac{5}{18}\).
Speed \(\displaystyle =54\times\frac{5}{18}=15\) m/s
Length of the train \(=15\times16=240\) m
