Question

the odometer of a car reads4000 km at the start of a trip and 4400 km at the end of the trip . if the trip took 16 hour calculate the average speed of the car in km h-¹ and mS-¹

Answer 1

Answer:

25 km/h or 6.9 m/s

Explanation:

Average speed = total distance covered upon total time taken

                          = (4400-4000)/16

                          =25 km/h

in m/s = 25 x 5/18 = 6.94 m/s (approx)

Answer 2

Answer:

25km/h , 90 m/s

Explanation:

covered distance = final - initial

=4400-4000 = 400km

toatal time =16 hrs

speed=400/16 = 25 km/h

in m/s =divide with 3.6=25/3.6 = 6.94444
