To solve, apply the formula:
`g r a d e = (rise)/(run) *100`
In the the problem, the rise represents the height of the ramp. So, to determine the horizontal run, plug-in grade=20 and rise=19 to the formula. Also, let x be the horizontal run.
Then, multiply both sides by x.
And, divide both sides by 20.
Hence, the horzontal run of the ramp is 95 feet.
