She can walk 24 miles in 3 hours
F(x)=12(3)ˣ
just find the slope
so for x=0
f(0)=12(3)⁰
f(0)=12(1)
f(0)=12
(0,12)
for x=5
f(5)=12(3)⁵
f(5)=12(243)
f(5)=2916
(5,2916)
the slope between (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
given
(0,12) and (5,2916)
slope=(2916-12)/(5-0)=2904/5
the rate of change is 2904/5
Is this your exact question? Can you explain a bit more what the question is asking?
