Question

on a model airplane, the scale is 5 centimeters=2 meters. if the model's wingspan is 28.5 centimeters, what is the actual wingspan

Answer 1

11.4 meters

because 28.5/1 * 2/5 simplifies to 5.7/1 * 2/1 which equals 11.4 meters

Answer 2

The actual wingspan is 11.4 meters .

Explanation:

Given that the scale is 5 centimeters = 2 meters, then the following proportion must be satisfied:

5 cm / 28.5 cm = 2 meters / x meters

x = 2*28.5/5

x = 11.4 meters

where x is the actual wingspan
