Answer:

10 hours

Step-by-step explanation:

We already have the equation, which is y = 30x + 20. Simply substitute 320 for y, and solve for x.

320 = 30x + 20

First, subtract 20 from both sides.

320 - 20 = 30x

300 = 30x

Now divide both sides by 30.

300/30 = x

10 = x

It will take about 10 hours for Robin to travel 320 miles.
