Question 812433: how to calculate the mileage of bike with the clue that if we fill the bike petrol tank full twice in 15 days Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! The milage is ( 15 days ) * ( miles/day ) / ( 2 tankfuls * gallon/tankful )
You have to know average miles driven each day and how
many gallons the tank holds.
