Question

a train is moving with a velocity of 45kilometre per hour the distance travelled by it in 1 hour 1 minute 1 second

Answer 1

45 km/h = 45 * (5/18)m/s = 12.5 m/s

1  hour = 3600 s

Distance travelled in one hour = 12.5 * 3600 = 45000m = 45 km
Distance travelled in one minute = 12.5 * 60 = 750m = 0.750 km
Distance travelled in one second = 12.5 *1 = 12.5m = 0.0125km
Distance travelled in 1 hour 1 min 1 sec = distance travelled in 3661 sec = 12.5 *3661 = 45762.5m  = 45.7625 km
