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
