Answer:
Average speed = 6 km/h and Average velocity = 0.67 km/h
Explanation:
Given that,
A dog walks 10 km north in 2 hours and then 8 km south in 1 hour.
(a) Average speed = total distance traveled divided by total time taken
Distance = 10+8 = 18 km
Total time = 2+1 = 3 h
Average speed = (18/3 )km/h= 6 km/h
(b) Average velocity = net displacement divided by total time taken
Let north is positive and south is negative
Displacement = 10+(-8) = 2 km
Total time = 2+1 = 3 h
Average velocity= (2/3 )km/h= 0.67 km/h
