The odometer on Melody's car read
45,920 at the beginning of her trip and
46,460 at the end of her trip. Her speed
averaged 54 miles per hour, and she used
20 gallons of gasoline. How many miles
per gallon did she average?

The table and the graph below each show a different relationship between the same two variables, x and y: a table with two columns and 5 rows is shown. the column head for the left column is x, and the column head for the right column is y. the row entries in the table are 4,100 and 5,125 and 6,150 and 7,175. on the right of this table is a graph. the x-axis values are from 0 to 10 in increments of 2 for each grid line. the y-axis values on the graph are from 0 to 300 in increments of 60 for each grid line. a line passing through the ordered pairs 2, 60 and 4, 120 and 6, 180 and 8, 240 is drawn. how much more would the value of y be on the graph than its value in the table when x = 12? 20 30 60 70
