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.

It moves the decimal place more efficiently than typing in *10^x Example: 3.14*10^2=314 3.14EE2=314

31.4/100 = .314
There are 60 minutes in one hour. Therefore, 314 minutes is equal to 314/60 = 5 remainder 14 or 5 hours 14 minutes.
5 hours and 14 minutes
Don't get cared by the decimal, it's just a point. It means: divide by 10^n where n is the number of digits after the decimal. So in this case, 3.14 means 314 / 10^2 = 314 / 100 so you are actually doing this 314/100 x 4 = 314 x 1/100 x 4. Multiplication is commutative so you might as well do 4 x 314, then divide by 100. So you should get 1256 / 100. To divide by 100, recall what decimal means, it's simply 12.56 :D
The answer varies according to the numerator in the expression. 1/314 = 0.003185 (approx).
It takes five hours, 14 minutes to travel 314 miles at 60 miles per hour.
