Question

question 1
which of the following correctly describes how to calculate the average speed of an object?
a average speed is equal to the change in velocity divided by the change in time.
b average speed is equal to the mass of an object times its acceleration.
c average speed is equal to total distance divided by total time.
d average speed is equal to total time divided by total distance.

Explanation:

The formula for average speed is the total distance traveled divided by the total time taken. Option A describes acceleration (change in velocity over change in time), option B is Newton's second - law ($F = ma$), and option D has the incorrect ratio for average speed.

Answer:

C. Average speed is equal to total distance divided by total time.
