Question

. A car covers a distance of 5 km in 20 mins. Find the velocity of the car in (a) km/min (b)
m/s (c) m/min (d) km/hr.

Answer 1

Answer:

Velocity = Displacement/Time

Displacement(or)Distance= 5km = 5000 m

Time= 20 min = 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
