Question

a train is moving with a velocity of 45km/hr . Calculate the distance travelled by it in 1 hour, 1 min, 1 sec

Answer 1

velocity = 45 x 5 / 18 

velocity = 12.5 m/s 

now time = 1hr 1min 1sec = 3661 sec 

distance = 3661 x 12.5 = 45762.5 m 

distance = 45.7652 km 

Answer 2

Distance travelled in one hour = 45 kms
speed = 45km/hr = 45 *1000/3600 m/s
speed = 12.5 m/s
distance in 1 min = speed*time
distance = 12.5*60 = 750m or 0.75 km
distance in 1 sec = 12.5 m
