Answer:
The length of the model will be 43.3 inches.
Step-by-step explanation:
Given : A scale model of a whale is being built. The actual length of the whale is 65 feet. The scale of the model is 2 inches : 3 feet.
To find : What will be the length of the model?
Solution :
The scale of the model is 2 inches : 3 feet i.e. [tex]\frac{2}{3}[/tex]
Let the length of model be 'x' inches.
According to question,
[tex]\dfrac{2}{3}=\dfrac{x}{65}[/tex]
Cross multiply,
[tex]2\times 65=3\times x[/tex]
[tex]x=\dfrac{2\times 65}{3}[/tex]
[tex]x=43.3[/tex]
Therefore, the length of the model will be 43.3 inches.
