The document discusses two examples of constant rates: Juan typing pages over time and Emily painting an area over time. It provides linear equations to model each situation and asks the reader to use the equations to complete tables of values, graph the relationships, and answer questions about specific time values.

Constant rate practice problems
- 2. 1. Juan types at a constant rate. He can type a full page of text in 3 1 2 minutes. We want to know how many pages, p, Juan can type after t minutes. Write the linear equation in two variables that represents the number of pages Juan types in any given time interval.
- 3. 2. Complete the table below. Use a calculator and round your answers to the tenths place. t (time in minutes) Linear equation: p (pages typed) 0 5 10 15 20
- 4. 3. Graph the data on a coordinate plane.
- 5. 4. About how long would it take for Juan to type a 5-page paper? Explain.
- 6. 5. Emily paints at a constant rate. She can paint 32 square feet in 5 minutes. What area, A, in square feet, can she paint in t minutes? Write the linear equation in two variables that represents the number of square feet Emily can paint in any given time interval.
- 7. 6. Complete the table below. Use a calculator and round answers to the tenths place. t (time in minutes) Linear equation: A (area painted in square feet) 0 1 2 3 4
- 8. 7. Graph the data on a coordinate plane.
- 9. 8. About how many square feet can Emily paint in 2 1 2 minutes? Explain.
