Answer:
Average speed=27.78m/s
Explanation:
Distance covered= Reading of odometer at end - reading of odometer at start =3000-2000 =1000km = 1000000m
Time taken=10h = (10×60×60)s =36000s
Average speed=Distance covered/Time taken
=1000000/36000= 27.78m/s

Answer:
It is given that the total distance travelled by the car is 2400 km-2000 km = 400 km, that is, 400000 m and the total time taken =8 hours, that is, 8×60×60=28800seconds..
Average speed in km/hr = total distance/total time = 400/8 = 50 km/hr.
Average speed in m/s = total distance/total time = 400000/28800 = 13.89 m/s.
