A truck has two fuel tanks: mainTank containing an initial amount of fuel in liters and additionalTank containing a reserve amount of fuel in liters.

The truck travels $10$ kilometers for every $1$ liter of fuel consumed from mainTank. Whenever $5$ liters of fuel are used from mainTank, $1$ liter of fuel is transferred from additionalTank into mainTank, provided that additionalTank contains at least $1$ liter of fuel.

Return the total distance in kilometers that the truck can travel until mainTank runs out of fuel.

Constraints:

• $1 \le$ mainTank, additionalTank $\le 100$
