Answer 2

Given length of train = 150 m

length of platform = 150 m

total distance = 150 + 150 = 300 m

speed of train = 30 km / hr

Convert speed from km /hr to m /s :
-------------------------------------------------
30km / h = 30 × 5 / 18 = 8.3 m/ s

Find the time taken :
----------------------------
time taken = total distance / speed

= 300 /8.3 = 36.1 seconds

= 36 seconds (approx . )

therefore,

the required time = 36 seconds







Answer : time = 36 seconds
