Question

a train passes 300 m long platform in 30 second and it crosses a signal on the station in 12 second find the length of the train​

Answer 1

Answer:

120m

Step-by-step explanation:

First, let’s find the speed of the train.

Speed = Distance / Time = 300 m / 30 s = 10 m/s

To convert into km/h, simply multiply the speed by 3600 (number of seconds in an hour)

10 m/s = 10x3600 m/hr = 36 km/hr

Now, to find the length of the train, let’s assume that the length of the signal is negligible. Since it takes 12 seconds for the train to cross the signal travelling at a speed of 10 meters per second, the length of the train is 120 m.

Speed of train = 36 km/hr

Length of train = 120 m
