Answer:

a) 12 feet per minute

b) 84 feet

c) 10 minutes

d)

Step-by-step explanation:

a) find the slope using furmula: y1 - y2/x1 - x2

24 - 12/2 - 1

12/1

12

12 feet per minute

b) 12 feet per minute so multiply the slope, 12 by 7

12 * 7 = 84

c) 12 * time, t, = feet deep

12 * t = 120

12t = 120

/12 /12

t = 10

10 minutes
