A train crosses a stationary pole in 3 minutes. It crosses a 600 meter long platform in 5 minutes. What are the length and the speed of the train?
Answer & explanation
Correct answer: option 2
Let length of train = L meter
Train cross a pole in 3 minutes i.e. train crosses its length in 3 minutes .
And train crosses 600 m bridge in 5 minutes , that means train cover 600 m in 2 minutes
2 minutes = 120 seconds
Speed = \(\frac{DIstance}{Time}\)
Speed of train = \(\frac{600}{120}\) = 5 m/sec
5 m/sec = 5 × \(\frac{18}{5}\) = 18 km/h
Distance traveled by train in 3 minutes = 5 × 180 = 900 m
So , length of train is 900 m and speed of train is 18 km/h .
