Correct Answer - Option 3 : 500
GIVEN:
A train running at the speed of 60 km/h crosses a pole in 30 seconds.
FORMULA USED:
Speed = Distance/Time
CALCULATION:
Speed of train = 60 km/h = 60 × 5/18 = 50/3 m/s
Time taken to cross the pole is 30 seconds
⇒ Length of train = 30 × 50/3 = 500 meters
∴ Length of the train (in metres) is 500 meters
