A car can go 5 miles with 2 gallons of gas because 5 times 10 is 50, so do the same with 2. 2 times 10 equals 20. Now, to find how much gasoline it take for 60 miles, you must divide 60 by 5, which is 12, so, now multiply 12 by 20 (gallons of gasoline you need in order to go 5 miles), which is 240.
Therefore, it take 240 gallons of gasoline to drive 60 miles.
Hope this helped :)
