Answer 1

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. $\frac{2}{3}$

Let the length of model be 'x' inches.

According to question,

$\dfrac{2}{3}=\dfrac{x}{65}$

Cross multiply,

$2\times 65=3\times x$

$x=\dfrac{2\times 65}{3}$

$x=43.3$

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