because then they won't be sore when they come back to earth.
12 hours = 1/2 day
2. Each day has 24 hours in it. 48/24=2
2 fifths of a day is 9.6 hours.
From 11 AM to 2 AM the next day is a total of 15 hours. This includes the 13 hours from 11 AM to midnight, plus an additional 2 hours from midnight to 2 AM.
First, calculate the total work done in hours: 10 people working 2 hours a day for 5 days equals 100 person-hours (10 people × 2 hours/day × 5 days). If 2 people work 5 hours a day, they complete 10 person-hours each day (2 people × 5 hours/day). To find out how many days it would take them to complete 100 person-hours, divide 100 by 10, which equals 10 days. Thus, 2 people will take 10 days to complete the same work working 5 hours a day.
They exercise for up to 2 hours each day, so that their bones and muscles don't become weak.
