Question

George the rat is a growing boy! When I first got him he weighed 11 pounds and could only run 1 mile before tiring. Now, a few months later, he weights 13 pounds! He can also run 7 miles before tiring. Assuming this growth is consistent, what is the function that describes the miles George can run before tiring, y, as it relates to his weight, x?

Answer 1

f(x) = 1x x = number of months
