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?
