Question

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

Answer 1

v=d/t =5/20 =1/4
(a) v = 0.25 km/min;

(b) v=5000m/20x60 s = 5000/1200 m/s
= 4.16 m/s.

(c) v= 5000m/20 min = 250 m/min

(d) v= 2 km/20/60 hr = 2x60/20 km/hr
= 6 km/hr

hope this will help...
