Answer: A. $D=3h+5$

Step-by-step explanation:

Given: The rate of increasing speed = 3 miles per hour

The distance she traveled before stopping = 5 miles

Let h represents the number of additional hours for hiking.

Then the equation that models the total distance 'D' Sarah travels after hiking for an additional h hours is given by :-

$D=3h+5$
