Subtract 3 hours, 50 minutes from 5 hours, 20 minutes.
2 hours, 20 minutes
1 hour, 40 minutes
1 hour, 30 minutes
2 hours, 30 minutes

1 hour 30 mins because you add up the minutes from both individually and then subtract.

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good
