Question

A car covers a distance of 5 km in 20 mins . Find the velocity of the car in km / min.

Answer 1

velocity = distance
                 time

V = 5 / 20

V=1/4

V =0.25 Km/Min

Answer 2

Distance = 5 km 
               = 5 × 1000
               = 5000 m //

Time       = 20 mins
               = 20 × 60
               = 1200 s //

We know that,
Velocity = Displacement / time
             = 5000 / 1200
             = 4.16 m/s //

You want answer in Km/ min
∴ Answer will be 5/20 
i.e ,
0.25 km/min //
