The way you round numbers is to look at the number immediately to the right of the place you want to round. In this case, you're looking at the number 4 because that is the next number after the first decimal place. If that number is 5 or greater, you round up to the next number; if it is less than 5 you stay the same. 4 is less than five so you leave the number 1 as a 1 and have 3.1 hours.
