MATHS In the Real World
Bike Trails The steepness of a bike trail, such as the Slickrock Trail in Utah, can be described by the ratio of the change in elevation to the horizontal distance traveled. In this chapter, you will use slope to compare the vertical change to the horizontal change between two points on a line in a coordinate plane.
What do you think? Suppose one bike trail rises 15 feet over a horizontal distance of 100 feet. Another trail rises 5 feet over a horizontal distance of 40 feet. Which trail you think is steeper? Why?
