Question

Sally has made a scale drawing of the airplane, in which the wingpsan is 10 inches and the tailspan is 3 inches. What is the actual tailspan of the airplane?

Answer 1

Answer:7.2

Step-by-step explanation: using the proportion 10/3 = 24/x we cross multiply and solve for x

Answer 2

My first impulse is to say you don't provide enough info with which to solve this problem. We need to know how many inches in the model correspond to 1 foot in the actual plane (that is, the scale factor). What is the scale factor here?
