B would be the correct answer
Answer:
Velocity = 120 km/h in north
Speed = 120 km/h
Explanation:
Given data:
Distance = 300 km north
Time taken = 2.5 hr
Speed and velocity = ?
Solution:
Speed = distance / time
Speed = 300 km / 2.5 h
Speed = 120 km/h
Velocity = change in position / change in time
Velocity = 300 km north / 2.5 hr
Velocity = 120 km/h in north
