Tables Graph Equations and Descriptions

Sumi and Jerome start riding their bikes at the same time, traveling in the same direction on the same bike path.  Sumi rides at a constant speed of 10 ft/s.  Jerome rides at a constant speed of 15 ft/s. Write an equation that expresses the distance, d, that Jerome has traveled as a function of the time, s in seconds, since he started riding her bike. (Write the equation you choose down on a piece of paper)

• d = 15s

• d = 10s

• s = 15d

• s = 10d
