Step-by-step explanation:

<u>Step 1: Define</u>

Boat A(3.1, -1)

Boat B(-4.1, -1)

<u>Step 2: Find distance </u><em><u>d</u></em>

Simply plug in the 2 coordinates into the distance formula to find distance <em>d</em>.

  1. Substitute [DF]:                    d = \sqrt{(-4.1-3.1)^2+(-1+1)^2}
  2. Subtract/Add:                       d = \sqrt{(-7.2)^2+(0)^2}
  3. Exponents:                           d = \sqrt{51.84}
  4. Evaluate:                              d = 7.2
