Wheelchair Ramp Problem (doc  pdf)
A company that makes wheelchair ramps needs to revise their catalogue to include the steepness of each ramp. Your company was given a subcontract to do this work. Within the current catalogue of wheelchair ramps, there are 8 models. You need to determine the steepness of each ramp and order them from least steep to most steep in the catalogue.
Here is your task:
 Compare each pair of ramps.
 Make an ordered list using all models (18), from least steep to most steep.
 Provide a mathematical justification for how you ordered your list.
 Describe any patterns you notice in the data.
