Proportional relationships (e.g. speed as the ratio of distance traveled to time taken) among different types of quantities provide information about the magnitude of properties and processes.
TERMS

Proportional relationship - relation of one dataset to another dataset
Directly - two quantities are proportional to each other (linear proportion)
Inversely - as one quantity increases the other decreases. Product of values is constant.
