The average rate of change is equal to 10 miles per hour.
<h3>What is the average rate of change?</h3>
It is the average amount by which the function changed per unit throughout that time period. It is calculated using the slope of the line linking the interval's ends on the graph of the function.
Given that the function is changing from point (30,2) to (20,1). The average rate of the change will be calculated as,
The average rate of change = ( 30 - 20) / ( 2 - 1)
Average rate of change = 10 miles per hour

Answer:
57.5 students
Step-by-step explanation:
Given that
The 30% students would be arrived by private car
So 15% would be travelled by taxi
And, the remaining i.e. 55% would be walk to school
Since the population of the school is 230
So by car, the students would be
= 230 × 0.30
= 69
By walk, the students would be
= 230 × 0.55
= 126.50
Now the more students would be
= 126.50 - 69
= 57.5 students
