Julie made a scale drawing of an Comanche helicopter. If the helicopter's rotors are 12 feet long, how long are they in her drawing? In the scale, 1 inch equals 4 feet.

Answer 1

First, we need to determine how many inches long the 12 feet rotor would be in the scale drawing.

Since 1 inch in the drawing represents 4 feet in real life, we can set up a ratio:

1 inch / 4 feet = x inches / 12 feet

Cross multiplying, we get:

4 * x = 1 * 12
4x = 12
x = 3

Therefore, the 12 feet long rotor would be 3 inches long in Julie's scale drawing.
