15. Mr. Taylor rides his moped down the country road in front of his house. His wife and their two sons ride bicycles in the opposite direction on the same road. If they leave at the same time and Mr. Taylor travels 24 mi/hr while Mrs. Taylor and the boys travel 8 mi/hr, how much time will pass before they are 24 mi apart?

step-by-step explanation: noo

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10

my best guesses would have to be either 4.5 or 2. p.s. if they're wrong, i'm so sorry for giving you the wrong answer.
