You are driving on a highway and are about 55 miles from a state border. You set your cruise control at 60 miles per hour and pl
kumpel [21]

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

The third one is a point with the first equation.

I had to simplify the second equation.
