If a person drives 390 miles at an average of 40 miles per hour, then their distance d from the destination (in miles) is a function of the number of hours h driven.

Graph attached.

Step-by-step explanation:

Assuming this complete problem:

"If a person drives 370 miles at 40 MPH then their distance d from the destination in miles is a function of the number of hours h driven

show equation graph and function"

We know from the definition of distance that

Where D represent the distance travelled on this case on mi, t the time in hours and v the velocity on this case in mi/h.

For this case if we want a function in terms of the time we can write this expression:

And since we know that the person travels 390 mi then we can find the total time spent on the travel like this:

approximately.

And the graph would be the figure attached,

i think that you should ask google for the answer to that problem because if we don't know it google does
