Question

If a train with a speed of60 km /hr crosses a pole in 30 second , What is length of the train (in metre)​

Answer 1

Step-by-step explanation:

speed-60; time -30 sec

length of train = speed/time

= 60/30

= 20m

Answer 2

Answer:

500 meters

Step-by-step explanation:

Converting the train’s speed

Train’s speed = 60 km/h

Train’s speed = 60,000 m / 3,600 s

Train’s speed = 50/3 m/s

Solving for the distance traveled in 30 seconds

distance traveled = Train’s speed * elapsed time

distance traveled = 50/3 m/s * 30 s

distance traveled = (1500 / 3) m

distance traveled = 500 m

Solving for the length of the train

Length of the train = distance traveled

Length of the train = 500 meters
