To calculate the longest time you can spend over dinner, first find the time it takes to complete the trip at the maximum speed. Divide the total distance by the speed: 549 mi / 65 mi/h = 8.4 hours. Since the trip starts 10.8 hours before the meeting, subtract the driving time from this to find the dinner time: 10.8 hours - 8.4 hours = 2.4 hours.
