Hello,

Your brainliest answer would be:

(10,5)

(15,6)
———————-

(10,5) (15,6)

6-5. 1
——. = ——
15-10. 5


M= 1/5

Y = 3

Y= 5+ 1/5 (x-10)

Y= 5+ 1/5x -2
-5. -5
Y= 1/5x + 3

1/5 feet per minute

3 feet is where it started


1/5 (30) + 3

5 goes into 30 six times

So 6 + 3 is 9

Your answer would be:

9 minutes!
