Question

Winton made a scale drawing of an arcade. An air hockey table, which is 5 feet wide in real life, is 4 inches wide in the drawing. What is the drawing's scale factor?

Answer 1

It always helps to draw a picture. Try to draw this. There are 3 sets of "4 inches" in each foot (each foot is 12 inches). Therefore this is a simple matter of 5 times 3 (five feet equals 5 times " three sets of 4 inches").

So 5 times 3 is 15. The scale factor is 1 to 15.
