Final answer:
The student's average velocity is calculated by dividing the displacement, 1.5 kilometers, by the time taken in hours, 0.2 hours, resulting in an average velocity of 7.5 km/h towards the north.
Step-by-step explanation:
The student's question asks to calculate the average velocity when skipping north for 12 minutes to reach a friend's house that is 1.5 kilometers away. Average velocity is defined as the displacement (change in position) divided by the time taken to make that change. Since the student's displacement is 1.5 kilometers north and the time taken is 12 minutes, we need to perform the calculation in consistent units. First, we convert 12 minutes to hours by dividing by 60, which is 0.2 hours.
Next, we calculate the average velocity using the formula:
Average Velocity = Displacement / Time Taken
Average Velocity = 1.5 km / 0.2 hours = 7.5 km/h.
The direction of the velocity is north since that is the direction of the displacement.
