Set up an equation to represent the distance a cheetah covered in terms of t minutes running at 70 mph.

Speed = distance / time

distance = speed * time

so we can write:-

d = 70t if t is in hours 

if t is in minutes then  it becomes

d = 70t / 60  = 7t/6

d = 7t/6      d wil be in miles and t is in minutes

Area of circle = pi * radius^2radius is given to be 1/2 inchespi * (1/2)^2 = pi/4 inches^2 = 0.785 inches^2
