Answer:
(1) 40 kmph
(2) 40 kmph north
Explanation:
Speed = Distance / Time
= 200 km / (5 hr)
= 40 kmph
Average velocity = Displacement / Time
[In given case magnitude of displacement is equal to total distance covered.]
= (200 km north) / (5 hr)
= 40 kmph north
Note: Average velocity is a vector quantity. It has both magnitude and direction.
