You are looking for the TOTAL time, so you should add those two fractions. Two methods that you can apply: ~First add the whole numbers. then add the fractions by finding the common denominator and adding the fractions together. ~Second, change them into improper fractions then add the fractions by finding the common denominator and adding the fractions together.
