Make sure that all of the units of measurements are in the same terms. For example, you cannot use distance that is expressed in "miles" and divide it by centimeters. You need all of your numbers to use the same unit of time.
Replace any remaining symbols with a number or alphabetical variable. This helps you get rid of confusing and unnecessary symbols that complicate your equation. After this, you want to have the velocity equation (velocity = distance traveled / time) expressed in numbers and letters.
Multiply time by velocity, but do not actually multiply the numbers. You only want to put time on the other side of the equals sign, so that you have this equation: time x velocity = distance traveled. You can leave all of your numbers in parentheses for now.
Divide distance traveled by velocity, leaving you with the equation: distance / velocity = time. Your velocity and distance should have the same unit of measure for distance. This will leave you with with only time, because the distance units should cancel each other out. For example, if you have 8 miles divided by 8 miles per hour, you will be left with one hour.
Ensure that your final number is expressed only in units of time. If it is not, you should go back to recheck your steps. If it is expressed in a unit of time, you have successfully solved for time in a velocity equation.
