A bike ramp has a slope of 1/4. What is the angle the ramps makes with the ground to the nearest degree?

The slope is equivalent to the rise over run. Since the slope of the bike ramp is ¼, the rise is equivalent to 1 and the run is equivalent to 4. To get the angle of the bike ramp make with the ground, let us use the equation tanθ = rise/run.

Therefore, tanθ = ¼.

Θ=tan-1 (1/4)

So the angle of the bike ramp is Θ = 14degrees
