1.26 hours
About 1.25 hrs
1 hour 15 minutes at 65 mph
225/82 = 2 and 61/82 hours
1.3 hours at 65 mph.
time = distance/velocity time = 700/82 = 8.53 hours
1 hour = 60 minutes. So 16 miles in 82 minutes = 60*16/82 = 11.71 mph
60 mph = 60 miles over 60 minutes (assuming a constant speed over that time of 60 mph) Therefore 1 mile is travelled in 1 minute. So, to travel 82 miles at 60 mph would take 82 minutes.
time = distance/speedtime = 281/82 = 3.43 hours = 3 hours and 25 minutes
Time = Distance/Speed so it would take 1700/82 = 20.73 hours (approx) assuming that the average speed of 82 mph could be sustained for that length of time. At an average speed of 82 mph, the answer implies no stop for rest or fuelling - quite an unrealistic assumption.
It will take about 75 minutes of total driving time at a constant 65 mph. Add some time for stops and delays.
