Pedro and Naomi begin to hike down a mountain at the same time.
They begin at different elevations and descend at different speeds.
The equation E = 4,200-800h gives Pedro's elevation in feet as a
function of time in hours. The table shows Naomi's elevation as she hikes
at a constant rate. Who has greater elevation at 1 hour?

a. Does Pedro or Naomi have greater elevation at h = 0? How much greater?
b. Who descends at a greater speed? How do you know?
c. The base of the mountain has 0 feet elevation. Does Pedro or Naomi reach the
base of the mountain first? Show your work.
