Answer

Answer:

A. $d = 825 - 165t$

Explanation:

Step1: Calculate speed

In the first - hour, the plane travels $825 - 495=330$ miles. So the speed $v = 330$ miles per hour.

Step2: Find remaining - distance formula

The initial distance to the destination is 825 miles. The distance traveled in $t$ hours at a speed of 330 miles per hour is $330t$ miles. The remaining distance $d$ to the destination is the initial distance minus the distance traveled. So $d = 825-330\times\frac{t}{2}=825 - 165t$.
