Answer:
114 3/8 gallons
Step-by-step explanation:
To solve the question, we multiply by the number of gallons and the amount travelled per gallon:
Let's convert all fractions to improper fractions:
15 1/4 = (15*4 + 1)/4 = 61/4
7 1/2 = (7*2 + 1)/2 = 15/2
Multiply the numerators and the denominators:
61/4 * 15/2 = 61*15/4* 2 = 915/8 = 114 3/8

The mean is the average. To find it, you add all of the numbers together.
2 + 8.7 + 11.9 + 3.3 + 4.2 + 2.2 + 13.4 = 45.7
Now you divide the total by the amount of numbers you added. Because you added 7 numbers, you divide 45.7 by 7.
45.7 ÷ 7 = 6.52 (This is the mean.)
To find the median you have to put all of the numbers in order of least to greatest.
2 2.2 3.3 4.2 8.7 11.9 13.4
The median is the number in the very middle. In this case, it is 4.2.
