The length of a model boat = 4 inches.
We are given scale factor = 24:1.
24:1 could be writte in fraction form as 24/1.
This represents that original boat is 24 times of model boat.
In order to find the length of the actual boat, we need to multiply length of by scale factor in fraction.
Length of a model boat × scale factor in fraction.
[tex]=4* \frac{24}{1}[/tex]
4 times 24 = 96.
Therefore, length of the actual boat is 96 inches.
