Elvis is driving Memphis to Chicago, a distance of 548 miles.
He drives 46 miles per hour for 4 hours.
At what rate must he drive to complete the entire trip in no more than 11 hours?
please include all the work and equations.
-----
After driving 4 hours he has 548-4*46 = 364 miles to drive.
-----
Equality::
rate = distance/time
-------
rate >= 364/11 >= 33.09 mph
