Question

A model of space shuttle Apollo Saturn V is created width a scale of 1: 144 if the actual space shuttle has a width of 62.4 feet, what is the width of the model, in inches.

Answer 1

The width of model is 5.2 inches

Solution:

Given that, model of space shuttle Apollo Saturn V is created width a scale of 1 : 144

The actual space shuttle has a width of 62.4 feet

Convert 62.4 feet to inches

1 feet = 12 inches

62.4 feet = 12 x 62.4 inches = 748.8 inches

Actual width = 748.8 inches

To find: Width of model in inches

From given,

Scale width : Actual width = 1 : 144

Let "x" be the scaled width

Then we can say,

Scale width : Actual width = 1 : 144

x : 748.8 = 1 : 144

In fractions,

$\frac{x}{748.8} = \frac{1}{144}\\\\x = \frac{748.8}{144}\\\\x = 5.2$

Thus the width of model is 5.2 inches
