Question

a car covers 40 km distance in to our next 40 km in 3 hour and last 60 km distance in 1 hour calculate average speed of car? ​

Answer 1

Answer:

Explanation:

Total distance = 40 km + 40 km + 60 km = 140 km

Total time = 2 hr + 3 hr + 1 hr = 6 hr

                     Average speed = total distance/total time

⇒                                v = 140/6 km/hr

                                  v = 23.33 km/hr
