Answer:
average velocity for the whole journey = 1.375 km/h
Step-by-step explanation:
we can take North as positive direction.
so, south is negative.
10 - 4.5 = 5.5 km.
total time (t) = 3 hrs + 1 hr = 4 hrs.
velocity = displacement / time
= 5.5 /4 = 1.375 km/h.
Hope this helps.
Mark as brainliest please. :D
