X=8
Set up proportions would give you: 10/3x+1 = 22/7x-1
With that in mind, cross multiply, which would give you: 10(7x-1) = 22(3x+1).
Turns into: 70x -10 = 66x+22. Then just solve for x
Based on your distance from the state border and the cruise control speed, the minimum and maximum hours you will have cruise control on is:
- Minimum - 1/3 hours
- Maximum - 1.5 hours
<h3>How long will cruise control be on?</h3>
You are 55 miles from the state border. You want to put the cruise control off within 35 miles of the border on either side.
This means that you might put it off in:
= 55 - 35
= 20 miles
The time to 20 miles is the minimum time the cruise control will be on:
= 20 miles / 60 miles per hour
= 1/3 hours
If you put it off 35 miles after the border, the distance is:
= 55 + 35
= 90 miles
The maximum time is:
= 90 / 60
= 1.5 hours
