Constant Rates of Change

“Sarah walks at a constant rate of 4 miles per hour. Create a table showing how far Sarah walks after 1, 2, 3, and 4 hours. A train travels at a constant speed. After 3 hours, it has traveled 180 miles. What is the train's speed in miles per hour? Show your work. Michael drives at a constant speed of 60 miles per hour. Write an equation that represents the relationship between the time Michael drives (t) and the total distance he travels (d).”
