daniel is on an airplane flying to a destination 825 miles away. after one hour, the pilot announces that the plane is 495 miles away from its destination airport. in another hour, the pilot announces that the plane will begin its half - hour descent for the final 165 miles. which equation represents the remaining distance, in miles, to the destination in terms of t, the time, in hours, since leaving the airport? o d = 825 - 165t o d = 825 - 330t o d = 825 + 165t o d = 825 + 330t
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 $d = 825-330\times\frac{t}{2}=825 - 165t$.
