Question

A car covers a distance of 5 km in 20 min . find the velocity of the car in A - km/min B - m/s C -m/min D -km/hr

Answer 1

Velocity= $\frac{Displacement}{Time}$

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

Answer 2

Answer:

Velocity= \frac{Displacement}{Time}

Time

Displacement

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
