Hi there! To solve this problem, you can do it by writing and solving a proportion. The proportion would be written like this: 378/18 = x/24. You do this, because you’re looking for the amount of miles you can go on 24 miles of gas and you already know the amounts of gallons, so they go at the bottom lines up with each other. Let’s cross multiply the values to get 9,072 = 18x. Now, divide each side by 18 to isolate the “x”. When you do that, x = 504. There. Kim can go 504 miles on 24 gallons of gas.
