Question 5 • Mathematics III
The table pairs stopping distances d of 20, 40, 60, 80, and 100 feet with speeds s of about 17.89, 25.30, 30.98, 35.78, and 40 miles per hour. Using s = 4√d gives 4√20 ≈ 17.89 and 4√100 = 40, matching the table. So the equation that best represents the data is “s is equal to 4 square root of d.”
