Question

an express train 180 metres long is running with a speed of 72km/h. In what time will it pass an electric pole

Answer 1

Answer:

Time = Distance/Speed

==== Distance = 180 m

=== Speed = 72 ×5/18= 20m/s

Time = 180/20 = 9 sec

Answer 2

It will pass an electric pole in 0.0025 hour

Step-by-step explanation:

Length of train = 180 m

1 km = 1000 m

180 m = 0.18 km

Speed of train = 72 km per hour

$Time = \frac{Distance}{Speed}$

$Time = \frac{0.18}{72}$

$Time= 0.0025 hour$

Hence It will pass an electric pole in 0.0025 hour
