Answer:

A

A

D

Step-by-step explanation:

The rate of change is

(0,30000) (4,0)

m = (y2-y1)/(x2-x1)

   = (0-30000)/(4-0)

    = -30000/4

     =-75000

A -7500

Second problem

(0,2) and (5,0)

m = (y2-y1)/(x2-x1)

   = (0-2)/(5-0)

   = -2/5

A -2/5

Third problem

(3,36) and (11,132)

m = (y2-y1)/(x2-x1)

   = (132-36)/(11-3)

   =96/8

   =12

D 12 miles per minute
