part 3 of 4
an automobile magazine reports the number of miles driven for different amounts of gas. which car travels the farthest on 1 gallon
click the icon to see the information about each cars gas mileage.
b. what do you know? what are you asked to find?
you know that car a gets 160 miles per 8 gallons, car b gets 145 miles per 5 gallons, and car c gets 72 miles per 3 gallons. yo
(type whole numbers.)

1. describe your plan or strategy to solve the problem. choose the correct answer below.

o a. i can make a ratio table for car b to find equivalent ratios and then compare cars a, b, and c.
o b. i can make a ratio table for car c to find equivalent ratios and then compare cars a, b, and c.
o c. i can use the graph to approximate equivalent ratios for car b and then compare cars a, b, and c.
o d. i can make ratio tables for cars b and c to find equivalent ratios and then compare cars a, b, and c.

Explanation:

To find which car travels farthest per gallon, we need to calculate the miles per gallon (unit rate) for each car, which can be done by creating ratio tables to find equivalent ratios for each car and then comparing them. All three cars' unit rates need to be determined and compared, so the plan must account for all three.

Answer:

D. I can make ratio tables for Cars B and C to find equivalent ratios and then compare Cars A, B, and C.
