The graph represents this situation: Cara jogs every morning, and after 30 minutes, she has run 3.5 miles. Homework Help ✎How is Cara’s speed represented on the graph?

Write a rule for Cara’s distance if

*t*represents the number of hours.If Cara continues to run at this rate, predict how far she will run in 4 hours.

The steepness of the line represents how fast Cara is going.

How far does Cara travel each hour? How does the distance traveled each hour relate to the total distance run and the time spent running?

*d* = 7*t*

Use the answer from part (b) to help solve.
