Answer 1

Answer:

Option 1) is correct

Step-by-step explanation:

Given: The graph shows the distance in miles, m, hiked from a camp in h hours.

To find: hourly interval that had the greatest rate of change

Solution:

Rate of change between two points refers to the vertical change divided by the horizontal change.

For hour 0 to hour 1:

rate of change = $\frac{2-0}{1-0}=2$

For hour 2 to hour 3:

rate of change = $\frac{4.5-3.5}{3-2}=1$

For hour 1 to hour 2:

rate of change = $\frac{3.5-2}{2-1}=1.5$

For hour 3 to hour 4:

rate of change = $\frac{5-4.5}{4-3}=0.5$

So, rate of change is greatest in interval: hour 0 to hour 1
