Question

The area of a square battlefield was 22,500 square miles. How long will it take a group of soldiers to cross the field diagonally at the rate of 3.2 miles/hour? Show work and explain

Answer 1

$\sqrt{22500} = s \\\ diagonal = s \sqrt{2} \\\ s = 150, \ diagonal = 150\sqrt{2} \\\ diagonal \approx 212.132 \\\ 212.132/3.2 \approx 66.291 \ hrs$
