1. A scale drawing of a school bus has a scale of 3 inch to 5 feet. If
the length of the school bus is 4 inches on the scale drawing,
what is the actual length of the bus?
Make a ratio of [tex]\frac{3 inches}{5 feet} =\frac{4 inches}{x feet} \\[/tex] and use cross multiplacation to get 3x = 20. Then, solving for x, x = 6.67 feet.
