Final answer:
To determine the average velocity for a trip from a friend's house to home, the displacement and time taken must be known. Without displacement information, the average velocity cannot be calculated. Average velocity differs from average speed as it is direction-sensitive.
Step-by-step explanation:
To calculate the average velocity on the way home, we need to know the displacement and the time taken for the journey. If the displacement is zero, as in the case of a round trip returning to the starting point, the average velocity would be zero. However, if the student is asking about a one-way trip from a friend's house to home, and the trip took one hour, the average velocity would be equal to the displacement (which is the straight-line distance from the friend's house to the student's home) divided by the time of travel. Unfortunately, as the question does not provide the displacement, we cannot compute the exact value of average velocity. It is important to note that average velocity is different from average speed, which is the total distance traveled divided by the total time taken, regardless of direction.
