Suppose the one-way distance is X miles.
The outward time = Distance/Outward speed = X/80 hours.
The return time = Distance/Return speed = X/70 hours.
The second journey was 1 hour longer, so X/70 - X/80 = 1
Multiply by 560: 8X - 7X = 560 so that X = 560.
Then outward time = 560/80 = 7 hours
return time = 560/70 = 8 hours
and
total time = 7 + 8 = 15 hours.
Infinitely many.I will use a variant of Zeno's paradox to illustrate this.Before you can drive a mile you must drive half a mile. So the event of driving a mile can be split into two sub-events of driving half a mile.But before you can drive half a mile you must drive a quarter of a mile. So the event of driving each half of a mile can be split into two sub-events of driving a quarter of a mile - making 4 sub-events in all.And then each of them can be split into two and so on, and on.Infinitely many.I will use a variant of Zeno's paradox to illustrate this.Before you can drive a mile you must drive half a mile.

If you drive for an hour, you have driven 45 miles. If you have driven for a longer or shorter time, you have driven more or less, respectively. You have to specify the amount of time to get the answer.
5 hours
It depends on how many hours you drive each day and your speed. If you averaged 50 MPH (miles per hour) and drove 14 hours each day, it would take you 2 days.
It depends on the speed at which you drive.
