Question

a A model of a ship is 6 inches long. The actual ship is 550 feet (6,600 inches). Find the scale factor used for the model.​

Answer 1

1 inch on the model represents 1,100 inches on the actual ship.

Explanation:

6600/6 = 1,100

Answer 2

`(1)/(1100)\rightarrow\text{This means for every 1 inch (for the model), it represents 1100 inches in real life}`

Explanation:

Let's set up a fraction to represent the scale factor.

`(Model)/(Actual\ Size)`

We can substitute the given values into the fraction.

`(6in)/(550ft)=(6in)/(6600in)`

Simplify the fraction.

`(1)/(1100)`
