Kenneth drew a scale drawing of an arcade. An air hockey table, which is 10 feet long in real life, is 5 inches long in the drawing. What scale did Kenneth use?
The scale can be found by dividing the length of the air hockey table in real life by the length of the air hockey table in the drawing.
Scale = length in real life / length in the drawing
Scale = 10 feet / 5 inches
First convert all measurements to the same units (in this case, inches):
Scale = (10 feet) * (12 inches/foot) / 5 inches
Scale = 120 inches / 5 inches
Scale = 24
Therefore, Kenneth used a scale of 24 for his drawing.
