The snail's distance and time in Exercise #1 showed a proportional relationship: PROPORTIONAL RELATIONSHIPS
Two variables m and n have a proportional relationship or are called proportional if their
ratio (or quotient) is always the same. In equation form:
m
-= a constant, i. e. m:n= a constant
n
The constant or unit rate is known as the constant of proportionality.
Exercise #2: For Exercise #1, what was the constant of proportionality? What is this constant
better known as?
