Question

A car covers adistance of 5 km in 20 minutes find the velocity of the car (a) kilometre / minute (b) metre /second (c) metre / minute (d)
kilometre /hour​

Answer 1

Velocity= displacement /time

Displacement(or)Distance= 5km = 5000 m

Time= 20min = 0.333 hr = 20×60=1200 sec

A ) velocity(km/min)=5km/ 20min =0.25 km/min

B ) velocity(m/s)= 5000m/1200s =4.1667 m/s

C ) velocity(m/min)= 5000 m/ 20 min = 250m/min

D ) velocity(km/hr)= 5km/0.333 hr =15 km/hr
