Question

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

Answer 1

Speed=distance/time

Distance= speed*time

1) When t= 1 hour

D= 45*1= 45 km

2) When t=1 minute

=1/60 hour

Then distance= 45*1/60

= 3/4 km or 750 m

3) When t= 1 second

D= 45* 1/3600

= 1/8o km or 12.5 m

I think its the right answer.
