find the slope of a road that rises 5 feet vertically for every 45-foot horizontal increase.

5 / 45 = 5 / ( 5 * 9 ) = 1 / 9

what is 5/45?

To find the slope of a road, you can use the formula: slope = rise / run.

In this case, the rise is 5 feet (the vertical increase) and the run is 45 feet (the horizontal increase).

To calculate the slope, divide the rise by the run:

slope = rise / run
slope = 5 feet / 45 feet

So, the slope of the road is 1/9 or approximately 0.111.
