Answer:
8 hours and 31 minutes
Explanation:
To get an average, you take the total time and divide it by the total days. Here, it would be 42 hours and 35 minutes divided by 5 days. You can convert the hours to minutes, and get 42x60=2520 plus the 35 minutes to get 2555 minutes. Divise that by 5 and you get 511 minutes per day. Since they're asking for hours and minutes, divide 511 by 60 to get 511÷60=8 with remainder 31.
