Question

A car covers a distance of 5 km in 20 min . Find the velocit in km/hr

Answer 1

Distance(displacement) =5km
Time =20min
=20/60 h
=1/3 h
Velocity = displacement/time
=5/(1/3)
=15 km/h
So, the velocity of the body = 15km/h

Answer 2

HI there !!


Distance = displacement  = 5km

Time = t = 20min = 1/3 hrs

Velocity  = displacement/time
               = 5/(1/3) = 5 x 3/1
               = 15 km/hr
Hence ,
 velocity = 15km/hr
