The average rate of change is 
Step-by-step explanation:
Given function that shows the population of a culture of cells,

Where, t represents the number of weeks.
Thus, the average rate of change in the population over the interval [0,24],

From equation (1),





Sixty-nine thousand, a hundred and eight?
Distance d is directly proportional to time t that he rides.
So d = kt where k is the constant of proportionality
Here k = his speed = 20 mph
So the required equation is d = 20t
