A student walks 0.85 km to class in 5 minutes and then back in 7.1 minutes What is his average velocity?

Since average velocity is total displacement over total time, the answer is 0m/s, because there is no displacement. (Remember, velocity has a direction unlike speed).

How can you extract the speed from velocity?
To extract the speed from velocity, which is a vector quantity, you take the magnitude of the velocity vector. The magnitude is the speed component of the velocity vector, indicating only the numerical value without any direction information. This gives you the scalar quantity of the speed.
Questions on motion for class 9?
What is the difference between uniform motion and non-uniform motion? Define speed and velocity. How are they different from each other? Explain the terms distance and displacement. How are they related to motion? What is acceleration? How is it different from velocity in terms of motion? How is the concept of motion essential in understanding the world around us?
How is average speed analogous to an average class grade?
Average speed is analogous to an average class grade in the sense that both represent a typical value for a set of data points. Just as average speed gives a sense of how fast something is moving overall, an average class grade provides a summary of how well students performed in a course. Both metrics can help in understanding the overall performance or progress in a system.

A student walks 0.7 km to class in 5 minutes and then back in 15.2 minutes What is his average velocity in ms?
Total distance is 1.4 km = 1400 m, total time is 20.2 minutes = 1212 seconds. Average speed = 1.155 m/s. Or is this a catch question to see if you understand the difference between speed and velocity? Velocity has a direction as well as a speed, this is called a vector quantity, and since you come back to the starting point, the average velocity is in fact zero. Note that I originally said speed is 1.155 m/s, not velocity.
