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 is 4 1/2 inches on the scale drawing, what is the actual length of the bus?

A) 45 feet
B) 10 feet
C) 15 feet
D) 20 feet

Answer 1

The actual length of the bus is 45 feet.

Step-by-step explanation:

To find the actual length of the bus, we need to use the given scale of 1/2 inch to 5 feet. This means that for every 1/2 inch on the scale drawing, the actual length is 5 feet.

Given that the length of the bus on the scale drawing is 4 1/2 inches, we can calculate the actual length using the proportion:

1/2 inch = 5 feet

4 1/2 inches = x feet (unknown actual length of the bus)

Using cross multiplication, we have:

(1/2) * x = (4 1/2) * 5

x = (9/2) * 5

x = 45 feet

So the actual length of the bus is 45 feet.
