Answer:
the constant rate of change of this table is 4 meters per second (option B)
Step-by-step explanation:
if in 10 seconds we moved 40 meters, each 1 of those seconds must have us 4 meters.
(simplest way to find unit rate: 40 / 10 = 4)
So, if you think of this as a graph, you will be going up 4 every time you move right 1.
This 4 [rise] / 1 [run] is called the "slope", which essentially has the same meaning as the constant rate of change.
So, the constant rate of change of this table is 4 meters per second (option B)
