Neighborhood block:
katen-ka-za [31]

Answer:

<u>The width of the neighborhood block is 0.05 or 1/20 miles</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Number of times Bijan run around the neighborhood block = 20

Total distance Bijan run = 8 miles

Length of the block = 3/20 = 0.15 miles

2. Use the formula for the perimeter of the neighborhood block and the reciprocal to find the width w of the city block.

Let's find the perimeter of the neighborhood block and the width, this way:

A. Rule of Three Direct for find the perimeter:

Laps              Distance

20                   8 miles

1                       x miles

x * 20 = 8

20x = 8

x = 8/20

x = 2/5 or 0.4 miles

B. Formula of the perimeter to find the width

Perimeter = 2 Length + 2 Width

Replacing with the real values we know:

0.4 = 2 * 0.15 + 2w

0.4 = 0.3 + 2w

0.4 - 0.3 = 2w

0.1 = 2w

w = 0.1/2

w = 0.05 miles

<u>The width of the neighborhood block is 0.05 or 1/20 miles</u>
