The remainder is 9........
R is equal to 450
first you subtract 5000 from each side
-2250=Rx5
then divid by 5
R=450
We can find this using the formula for arc length (where
is the radius of the circle and
is the central angle in radians):

In our problem, we are given
. This means that:

The measure of the angle is 1.5.
530 miles are travelled for every hour passed?
