You have to use the Time Distance and Speed method and do 200 divided by 75 which is 2.67 (rounded)
2 hours, 40 minutes
At 65 mph, 3 hours 4 minutes. This is the actual driving time at that speed and does not include stops or delays.
200 miles each way.
To cover the 200 miles will require at least 3 hoursand 4 minutes of driving time if you maintain a steady 65 mph. You will have to add time for stops, detours and other delays.
About 8.3 mph at that rate of travel.

3 hours 4 minutes. This is the total driving time at that speed and excludes stops or delays.
About 2 hours 40 minutes. This is the driving time at that speed and does not include slowing, accelerating or stopping during the trip.
Time = Distance / Speed so 200 miles / 55 mph = 3.63.. hours
A minute for every 5 miles.
Distance = Rate * Time or, for our purposes Time = Distance/Rate Time = 550 miles/65 mph ( as you see miles cancels and leaves hours ) Time = 8.5 hours spent driving
2 hours 40 minutes. This is the total driving time at that speed and excludes stops or delays.
It will take about 4 hours of total driving timeat a constant 50 mph. Add some time for stops or delays.
