Two cyclists, A and B, are going on a bike ride and are meeting at an orchard. They left home at the same time. Functions A and B give their distance from the orchard, in miles,
after riding for x hours. The functions are defined by these equations:
A(x) = -21% + 48.5
B(x) = -16.8x + 42
For each question, explain or show your reasoning.
a. Which cyclist lives farther away from the orchard? How do you know?
b. Who will get to the orchard first? Explain your reasoning.
