Question

A train is moving with a velocity of 45 km per hour calculate the distance travelled by it in one hour one second one minute

Answer 1

Answer:

First of all it must be displacement not distance as velocity formula has only displacement in it, not distance

Explanation:

a.displacement= velocity*time

                =45*1= 45 km

 b. 1 minute = 1 hour/60

displacement= velocity*time

              = 45*1/60 = 0.75 km = 750 m

c. 1 second = 1 hour/3600

   displacement= velocity*time

                 = 45*1/3600 = 0.0125 km = 12.5 m
