Let’s check out your problem:

Jerry has a large car which holds 2222 gallons of fuel and gets 2020 miles per gallon. Kate has a smaller car which holds 16.516.5 gallons of fuel and gets 3030 miles per gallon. If both cars have a full tank of fuel now and drive the same distance, in how many miles will the remaining fuel in each tank be the same?

Full solution

Q. Jerry has a large car which holds 2222 gallons of fuel and gets 2020 miles per gallon. Kate has a smaller car which holds 16.516.5 gallons of fuel and gets 3030 miles per gallon. If both cars have a full tank of fuel now and drive the same distance, in how many miles will the remaining fuel in each tank be the same?
  1. Calculate Total Distance: Calculate the total distance Jerry's car can travel on a full tank.\newlineJerry's car gets 2020 miles per gallon and holds 2222 gallons.\newlineTotal distance = 2020 miles/gallon ×\times 2222 gallons\newline= 440440 miles
  2. Calculate Total Distance: Calculate the total distance Kate's car can travel on a full tank.\newlineKate's car gets 3030 miles per gallon and holds 16.516.5 gallons.\newlineTotal distance = 30miles/gallon×16.5gallons30 \, \text{miles/gallon} \times 16.5 \, \text{gallons}\newline= 495495 miles
  3. Determine Difference: Determine the difference in the total distance each car can travel.\newlineDifference = 495495 miles - 440440 miles\newline= 5555 miles
  4. Calculate Fuel Used: Calculate the amount of fuel each car uses to travel the 5555-mile difference.\newlineFor Jerry's car: 55 miles20 miles per gallon\frac{55 \text{ miles}}{20 \text{ miles per gallon}}\newline= 2.752.75 gallons\newlineFor Kate's car: 55 miles30 miles per gallon\frac{55 \text{ miles}}{30 \text{ miles per gallon}}\newline= 1.83331.8333\dots gallons
  5. Subtract Remaining Fuel: Subtract the used fuel from each car's full tank to find the remaining fuel when they have traveled the same distance.\newlineFor Jerry's car: 2222 gallons - 2.752.75 gallons\newline= 19.2519.25 gallons remaining\newlineFor Kate's car: 16.516.5 gallons - 1.83331.8333\ldots gallons\newline= 14.666614.6666\ldots gallons remaining
  6. Find Equal Remaining Fuel: Realize a mistake has been made. The question asks for the point at which both cars have the same amount of fuel remaining, not when they have traveled the distance equal to the difference in their total capacities. We need to find a distance where the remaining fuel in both tanks is equal after driving the same distance.
