Question

a train whose length is 150 M passes a telegraph pole in 10 seconds find the speed of the train in kilometre per hour

Answer 1

heya user!!
speed of the train in m/s =150/10=15m/sec
So in km/hr speed of the train = 15*18/5=18*3=54 km/hr ----- that's the required answer ⭐
hope it helps
( Just remember if you wanna convert m/s into km/hr multiply the speed in m/s by 18/5 and you'll get the required answer)
