So you would take 260 miles and divide by 4 hours to get 65 mph. And since the rate slows by 20%, you would subtract 13 from 65 giving you 52. So the new speed of the tornado is 52 mph. And take that and multiply it by 2 hours to get 104 miles. The correct answer is B.
One value: would be a single valued function, or just one answer.
Real numbers would be: natural numbers, whole numbers, integers, rational numbers (fractions and repeating or terminating decimals), and irrational numbers.
