Answer:
Rate of change of the ramp's incline is 3.
Step-by-step explanation:
Since the points on ramp F and G have the coordinates (4, 12) and (6, 18)
Now the slope of the ramp passing through two points will be the rate of change of the ramp's incline.
Slope = [tex]\frac{y-y'}{x-x'}[/tex]
= [tex]\frac{18-12}{6-4}[/tex]
= [tex]\frac{6}{2}=3[/tex]
Therefore, rate of change of the ramp's incline is 3.
