The horizontal distance is given by dividing the vertical height by the grade (which is a ratio of vertical rise to horizontal run).

Horizontal distance = vertical height / grade
Horizontal distance = 250 / 0.27
Horizontal distance ≈ 925.9 ft

Rounding to the nearest foot gives us 926 ft.

The Grade of a Highway Up a Hill Is 27
