Which proportion is used to determine highway travel distance using the same gas tank as city driving?

(25/235) = (x/30)
(25/55) = (x/325)
(25/325) = (30/x)
(25/55) = (325/x)

The correct answer is: (25/325) = (30/x)

To determine the correct proportion for calculating highway travel distance using the same gas tank as city driving, one needs to understand the relationship between distance, fuel efficiency, and the amount of fuel consumed. In the given context, the proportion used is C, which states (25/325) = (30/x). Here’s how this works: 1. The first part of the proportion (25/325) refers to the fuel consumption for city driving, where one has data indicating that 25 miles can be driven with 325 units (likely gallons or liters). This serves as a basis for understanding fuel efficiency in a city driving scenario. 2. The second part of the proportion (30/x) represents the highway driving scenario. Here, 30 miles could be the distance driven on the highway with the same tank of gas, and x would represent the total units of fuel consumption needed to cover that distance. By establishing this proportion, one can solve for x, which reflects the amount of fuel required for highway driving over a distance of 30 miles based on the total fuel capacity used during city driving. Thus, this proportion is effectively used for scaling the city driving fuel consumption to project what the fuel usage would be for highway driving, under the assumption that
