Answer:

The actual length is 45 feet.

Step-by-step explanation:

I. When 1/2 per 5 feet

2 * 1/2 = 5 * 2

1 per 10 feet

II. Find actual length of the bus

4( 1/2 ) => 4 and 1/2

Find actual 4

      1  = 10

4 * 1 = 10 * 4

      4 = 40

The actual of 4 scale is 40 feet

III. Find sum of actual length by

4 (1/2) = x

4(1/2) = 40 + 5

= 45

Or you can use 4(1/2) = 9/2 = 1/2 + 1/2... 9 times or 5 * 9 = 45 feet.

That makes the actual lenght is 45 feet.

Hope that help :)
