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
