Question

Anna designs model planes. Her latest scale drawing is a scale of 1 in. : 24 in. In this drawing, the wing of a plane is 4 inches long. For an advertisement, Anna has to make a larger drawing. In this drawing, the wing of the plane is 10 inches long.

a. What is the actual length of the wing in feet? Explain.
b. What scale did Anna use on the advertisement drawing?

Answer 1

The actual airplane wing is 24 times bigger than her first drawing.
24*4=96

The actual airplane wing is 96 inches long.
96/12=8
The actual airplane wing is 8 feet long.

The scale of her advertisement is 10 in : 96 in.

That reduces to 5 in :48 in.
