Question

A scale drawing of a school bus has a scale of 1/2 inch to 5 feet. If the length of the school bus in 4 1/2 inches on the scale drawing,what is the actual length of the bus

Answer 1

Let 4_1/2 = 9/2 inches as an improper fraction.

(9/2) ÷ (1/2)

(9/2) (2/1)

9 x 5 = 45

The bus is 45 feet in length.

Answer 2

The actual length of the is 45 feet.

Explanation:

The scale means each 1/2 inch is equivalent to 5 feet. So if in the drawing the length of the school bus is 4 1/2 inches, which would be 4.5, then we used the following equations:

0.5 inch = 5 feet

4.5 inch = X (real length of the bus in feet)

X =\frac{4.5 inch * 5 feet}{0.5 inch}

X =45 feet
