Question

the speed of the train is 54 kilometre per hour it takes 24 seconds to cross a 260 long channel what is the length of the train​

Answer 1

Step-by-step explanation:

The train crossing the platform means that

At the time the timer is started, the train’s front most part is at the starting of the

platform.

≈At the time the timer is stopped, i.e, 24 seconds later, the train’s rear most part is at

the end of the channel.

≈This means that in 24 seconds, the train has traveled a distance equal to the length of the channel + the length of the train.

54 km/h = 20 m/s. In 24 seconds at this speed, the train travels 20 x 24 = 480 meters.

Length of platform + length if train

= 480m.

Length of train = 480 - length of channel

= 480–260

=220m
