Question
A train travelling at a speed of 90 kmph, crosses a pole in 10 sec. the length of the train is:
Solution
The speed of the train is given in km/h, but the time is given in seconds. So, first we need to convert the speed from km/h to m/s.
We know that 1 km = 1000 m and 1 hour = 3600 seconds.
So, 90 kmph = 90 * 1000 / 3600 = 25 m/s.
The train crosses a pole in 10 seconds. When a train crosses a pole or a stationary object, the distance covered is equal to the length of the train.
We know that speed = distance/time.
We can rearrange this formula to find the distance: distance = speed * time.
So, the length of the train = speed of the train * time taken to cross the pole = 25 m/s * 10 s = 250 m.
So, the length of the train is 250 meters.
