Question

Answer 1

Answer:

The actual airplane is 25 ft long

Step-by-step explanation:

Scaling

Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing by a constant factor.

The scale used to draw an airplane is:

2 in = 5 ft

The scale factor is, then:

5 ft / 2 in = 2.5 ft/in

The actual airplane's length can be obtained by multiplying the scaled size by the scale factor:

10 * 2.5 = 25 ft

The actual airplane is 25 ft long
