Your grandma lives 300 miles away. to go to her house, your average is 60 miles per hour(60mph). on the way home, you travel a bit slower at 50 miles per hour (50mph). what was your average speed for the entire round trip?

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
