Question

A builder needs to build a ramp to a house. It starts at 10 meters from the house, and when it reaches the house it is 0.8 meters higher than where it started.

Building regulations state that the maximum gradient allowed is 0.07. 

Will he be able to build the ramp straight to the house? If not suggest changes he would have to make to the ramp.

 

Answer 1

The gradient is the same as the slope.

Slope = change in  vertical / change in horizontal

Slope of ramp = 0.8 / 10

Slope of ramp = 0.08

 

This is more than the 0.07 maximum allowed.

 

The builder could start the ramp father away from the building.
