Question

If an airplane in a 2in .5ft scale drawing is 10 in long, how long is the actual airplane?

A) 20 feet
B) 25 feet
C) 5 feet
D) 12.5 feet

Answer 1

The actual length of the airplane is 2.5 feet.

Step-by-step explanation:

To find the length of the actual airplane, we can use the concept of scale drawing. According to the given scale, 2 inches in the drawing represents 0.5 feet in real life. Therefore, to find the actual length of the airplane, we can set up a proportion:

2 inches ÷ 0.5 feet = 10 inches ÷ x feet

Cross-multiplying, we get:

2x = (0.5) * 10

Simplifying, we find:

x = 2.5

Therefore, the actual length of the airplane is 2.5 feet.
