Answer:
20ft
Explanation:
You multiply the model length by the scale factor to find the actual length. <u>If the scale factor is less than zero, then the actual size will be smaller than the model</u>. Therefore, your answer would be 20ft.
Specifically, the scale factor is .8 if the actual size is 20ft, 1 if the actual size is 25ft, and 1.2 if the actual size is 30ft.
180 + 30x = 60 + 50x
⇒ 20x = 120
⇒ x = 6 minutes
