1. An airplane on autopilot took hours to travel kilometers. What is the unit rate for kilometers per hour? 2. What is the unit rate for 360 miles per 18 gallon if you travel miles on gallons of fuel? Use pencil and paper. Describe another unit rate that you could find for this situation. Explain the meaning of that unit rate.

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
