Question

a train has a speed of 45 km per hour calculate its speed in metre per second​

Answer 1

Answer:

Given speed of the train = 45 km/h

Now, we have to convert 45 km/h in meter A.S.P (as per question)

1 km = 1000 m and 1 hour = 60 x 60 seconds

Now, by substituting the values, we will get:

45 km/h = 45 x 1000 m / 60 x 60 sec

⇒ 12½ m/sec (or) 12.5 m/sec

∴ 12½ m/sec (or) 12.5 m/sec
