Question

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

Answer 1

Answer:

s=5 km

t=20 min

a. 5*20 km/ min=100 km/min

b. 5*1000/60*20=5000/1200= 4.16m/sec

c. 5*1000/20= 250 m/min

d. 5/(20/60)=5/1/3=5*3=15km/ h

Answer 2

distance = 5km

time = 20min

velocity = distance/time

5km/20min

0.25km/min

a) 0.25 km/min

b) 1 min = 60 s

1 km = 1000 m

=0.25*1000/60 km/s

= 4.16 m/s

c) 1 km = 1000 m

=0.25*1000m/min

=250m/min

d) 1km/hr = 18/5 m/s

= 4.16*18/5 km/hr

= 14.78 km/hr..

hope it's corret
