Question

a train 180 metre long is running at a speed of 108 km per hour what is the time taken by train to cross an electric pole​

Answer 1

Answer:

Step-by-step explanation:

change 108 km /h in m/s by multiplying  5/18 =108 ×5/18 ⇒54 ×5 /9 m/s  , v=s/t ,  t = 180 ×9 /54×5  =6 s

Answer 2

Answer:

d=180m

s=108

therefore time taken = 180/108*1000 = 1/600

1*60*60/600=36/6=6s
