Answer 1

The length of the model will be 43.3 inches.

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.
`(2)/(3)`

Let the length of model be 'x' inches.

According to question,

`(2)/(3)=(x)/(65)`

Cross multiply,

`2* 65=3* x`

`x=(2* 65)/(3)`

`x=43.3`

Therefore, the length of the model will be 43.3 inches.
