The shortest horizontal distance that the ramp can span is 2.5 feet.

What is the angle of incline?

The angle of incline refers to the angle that the inclined plane makes  with the horizontal.

We can be able to obtain the shortest horizontal distance that the ramp can span using the trigonometric ratios as follows;

cos 4.76° =  2.5 /x

x = 2.5 /cos 4.76°

x = 2.5 feet
