Question

an Express train is moving with a velocity of 120 kilometre per hour how much distance will it cover in 45 second​

Answer 1

speed = 120 km/h

d=?

time =45sec

convert time to hr or( km/h To m/s)

1sec=1/3600h

45sec=45/3600

=0.0125h

distance=speed ×time

d=0.125*120

=1.5 km

other method

120 km/h = 33.3m/s

t=45s

d=33.3....*45=1500m/s
