The area of Miguel’s rectangular garden is 450 square feet. The garden is 9 feet wide.

Daniel [21]

Answer: 118 feet

formula:

$\to t^2=\frac{pt}{D} \times \frac{Dt}{P}\\\\_{where}\\\\\text {t= time = noon - sunrise}\\\\\text{p= pat's speed}\\\\\text{D= Dana's speed}\\$

$\to t^2= 11.25 \times 5\\\\$
