Question

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

Answer 1

Distance = 5km = 5000m

Time = 20 mins = 20×60 = 1200s = 1/3hr

a) Speed in km/min = 5km/20min

=> 1/4 => 0.025km/min

b) Speed in m/s = 5000m/1200s

=>12/50 =>4.167m/s

c) Speed in m/min = 5000m/20min

=>250m/min

d) Speed in km/hr = 5km/1/3

=> 15km/hr

Cheers!

Answer 2

(A) Dist = 5 km

    time = 20 mins

∴ Speed = 5/20 = 1/4 = 0.25 km / min

(B) Speed = 5000/1200 = 4.16 m / s

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

(D)Speed = 15 km/hr
