Question

4. Driving on the highway, you can safely drive 65 miles per hour. How far can you drive in ‘h’ hours? What is the domain of the function which defines this situation?A) 65B) the number of hours you driveC) the distance you driveD)the amount of gas you use

Answer 1

`\text{ The number of hours you drive.}`

Explanation:

For distance, we can apply the following equation:

`\begin{gathered} d=s*h \\ where, \\ s=\text{ speed} \\ h=\text{ hours} \end{gathered}`

Since we know that we can safely drive 65 miles per hour, the domain will be defined by the number of hours you drive:

`d=65h`
