Question

how is average speed analogous to an average class grade?

1. - / 4 points

does a negative acceleration always mean that an object is slowing down?
yes
no

Explanation:

Average speed is calculated as total distance divided by total time. It gives an overall measure of how fast an object was moving over a period, without indicating the speed at every instant. Similarly, an average class grade is calculated as the sum of all grades divided by the number of grades. It gives an overall measure of a student's performance in a class, without indicating the performance on every individual assignment or test. Both are summary measures that smooth out the details of individual - level variations.

Answer:

Average speed (total distance/total time) and average class grade (sum of grades/number of grades) are both summary measures that represent an overall value over a set of data (distance - time intervals for speed, grade - assignment pairs for grade), ignoring the details of each individual component.
