To determine how many feet are in a 5K (3.1 miles), we can set up the proportion based on the fact that there are 5,280 feet in one mile.

First, we can calculate the number of feet in 3.1 miles:

  1. Identify the number of feet in one mile:
    1 mile = 5,280 feet

  2. Multiply the number of miles (3.1) by the number of feet in one mile:
    3.1 miles × 5,280 feet/mile = 16,368 feet

Thus, the total number of feet in the 5K race is 16,368 feet.

To complete the proportion and determine how many feet are in the 5K race (3.1 miles), we can set it up like this:

Let \( x \) be the number of feet in 3.1 miles. The proportion can be set like this:

\[ \frac{3.1 \text{ miles}}{1 \text{ mile}} = \frac{x \text{ feet}}{5280 \text{ feet}} \]

Now, we can solve for \( x \):

  1. Cross-multiply:

\[ 3.1 \text{ miles} \times 5280 \text{ feet} = 1 \text{ mile} \times x \text{ feet} \]

  1. Calculate:

\[ x = 3.1 \times 5280 \]

  1. Performing the multiplication:

\[ x = 16368 \text{ feet} \]

So, the completed proportion is:

  • Drop target 1: 3.1
  • Drop target 2: 1
  • Drop target 3: 5280

Therefore, there are 16,368 feet in the 5K race.
