Question

a train speeds past a pole in 15 seconds and a platform 100 M in 25 seconds find the length of the train​

Answer 1

Answer:

In extra 10 sec train passes the platform so

speed of train 100/10=10m/s

so length of train 15*10=150 meter

Answer 2

Answer:

60 m

Step-by-step explanation:

if it passes by a platform 100 m in 25sec so it moves with velocity 4m/sec

so it means that its length is = 15.4=60

as V= d/t
