Question

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

Answer 1

Answer:(a) 0.25 km/min (b) 4.17 m/s (c) 250 m/min (d) 150 km/hr

Explanation:

distance travelled = 5 km =(5 * 1000 )m = 5000m

Time taken = 20 minutes =( 20 * 60 ) sec = 1200 sec = (20/60) hr = 0.33hr

(A) velocity (km/min) = distance travelled / time taken = (5/20)km/min = 0.25 km/min

(B) velocity (m/s) = (5000/1200) m/s = 4.17 m/s

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

(D) velocity (km/hr) = ( 5*60/20) km/hr = 150 km/hr

Answer 2

Answer:

Answer:(a) 0.25 km/min (b) 4.17 m/s (c) 250 m/min (d) 150 km/hr

Explanation:

distance travelled = 5 km =(5 * 1000 )m = 5000m

Time taken = 20 minutes =( 20 * 60 ) sec = 1200 sec = (20/60) hr = 0.33hr

(A) velocity (km/min) = distance travelled / time taken = (5/20)km/min = 0.25 km/min

(B) velocity (m/s) = (5000/1200) m/s = 4.17 m/s

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

(D) velocity (km/hr) = ( 5*60/20) km/hr = 150 km/hr
