The question indicates that Avery will drive 340 kilometers in 3 hours.
30 hours
12 hours if you drive at 100km/hr straight.
80 hours
7.88 hours
784 / 120 = 6.533' hours. Or about 6 hours 32 mins.
The distance is apparently 388 kilometers. That is about 4 hours drive.
2,0869 hours= 2h5m13s
About 2 hours
It depends on how fast you are going!
After Hours - Avery Parrish song - was created in 1940.
Time = Distance/Speed = 6000/80 = 75 hours. That assumes that you can drive 75 hours averaging that speed without a break!
To calculate the time it would take, you need to resubmit your question advising on what speed your travelling.
