Explanation:
Dear, Students
Average speed = Total distance/ Total time taken
Journey start at = 10532km
Journey ends at = 10850km
Time = 12 hour = 12x60 min = 720 min
also, time = 12x 3600s = 43200s
(1) Average speed (In km/h)
= 10850 _ 10532/12 = 26.5 km/h
(2) Average speed (in km/h)
= 10850 _ 10532/720 = 0.44 km/h
(3) Average spped (in km/s)
10850 _ 10532/43200 = 7.36 x 10-3 km/s
