Answer 1

Answer:

The answer is "4.5"

Step-by-step explanation:

Given value:

$\text{time = 11:15 PM}$

formula:

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

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

      $= 56.25$

$\to t= 7.5$

if the sunrise value is =12

$\to sunrise = 12- 7.5$

                 $= 4.5$
