Answer:
The scale for a model that is 30 inches long is 449.2 inches.
The scale for a model that is 2 feet long is 561.5 feet.
Step-by-step explanation:
Consider the provided information.
The USS Enterprise was 1,123 feet in length.
Part (A) What is the scale for a model that is 30 inches long?
1 feet = 12 inches.
First convert the length of USS enterprise in inches.
1×1,123 feet = 12×1,123 inches
1,123 feet = 13476 inches
Divide original length with the length of model.
The scale for the model is:
Hence, the scale for a model that is 30 inches long is 449.2 inches.
Part (B) What is the scale for a model that is 2 feet long?
Since, both the units are in feet, so simply divide original length with the length of model.
The scale for the model is:
Hence, the scale for a model that is 2 feet long is 561.5 feet.
