Answer:
0 hours
Step-by-step explanation:
If you have driven 10 hours a day for five days, the total number of hours driven will be calculated as 10 times 5, so:
10 hours x 5 days = 50 hours
It means that those five days you drive 50 hours which is the maximum number of hours in a 6 day period, so on the sixth day you can't drive.
Therefore, the maximum number of hours that you could drive on the sixth day is 0 hours.
