Question 439204: If I can drive 50 miles on $10 worth gas at $4.00 per gallon, how much will it cost me to drive 450 miles? Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! 450 miles is 9 times as far, so it's 9 times the cost.
$10*9 = $90

The price is not relevant given the other 2 factors.
