Question

a train a 160m long crosses a platform of 160m length in 16 seconds what is the speed of the train?

please explain the answer​

Answer 1

Answer:

Step-by-step explanation:

Speed = distance travelled / time taken

Here, distance travelled = length of the train + length of the platform

Because your train will be considered crossed the platform only after its full length has crossed the platform

Therefore, distance = 160+160 = 320m

Time = 16s

Speed = distance / time

Speed = 320/16 = 20m/sec

Now, convert it to km/h

Use the basic concept , 1m = 1/1000km

And 1sec = 1/3600 hr (1hr = 60min = 60*60sec)

Therefore, our speed = (20*3600)/1000 = 72km/hr

Answer 2

Answer:

72km/hr
