Answer:
V = D/t = 10 / 20 = 0.5 mile per min
V = D/t = 20/30 = (2/3) mile per min
V = D/t = (10+20)/ 50 = (3/5) mile per min
Too add mixed numbers, first convert them to improper fractions:
34/5 + 53/10
Next, find a common denominator, which in this case is 10.
Convert 34/5 so that it has a denominator of 10 by multiplying the ENTIRE fraction by 2: 68/10
68/10 + 53/10 = 121/10
You can either give your answer in the form of an improper fraction: 121/10, or a mixed number 12 1/10
