F(1) = -5(1)^2+2(1)+9 = 6
f(2) = -5(2)^2+2(2)+9 = -9
So, because f(1) = 6 is positive and f(2) = -9 is negative, f(1) > f(2).
f(1) is greater than f(2)!
sprints: 1/8 of 74 1/2 = 74.5 divided by 8=9.3125
Hunts: 3/4 of 57 3/4= 57.75 divided by .75=77
9.3125 + 77=86.3125 86.3125 divided by 2= 43.156 mph average speed
