Question

A man walks 7 km in 2 hours and 2 km in 1 hour in the same direction.
What is the man’s average velocity for the whole journey?
(a) 3 km/h
(b) 2 km/h in the same direction
(c) 2 km/h
(d) 3 km/h in the same direction

Answer 1

Total displacement = 7 + 2 = 9 km (same direction).
Total time = 2 + 1 = 3 h.
Average velocity = displacement / time = 9/3 = 3 km/h in the same direction.

Answer: (d) 3 km/h in the same direction.
