Answer: Option C

40 ft/in

Step-by-step explanation:

We know that:

model rocket = 3 inches long

real rocket = 120 ft long

To find the unit rate that describes the relationship of the real rocket to the model rocket, you must divide the length of the real rocket by the length of the model rocket:

r =\frac{120\ ft}{3\ in}

r =40\frac{ft}{in}

This means that every inch in length of the model rocket equals 40 feet of real rocket length

The answer is the option C
