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 $\le 100$

Input: mainTank = 10-int, additionalTank = 1-int
Output: 110-int
Explanation: The truck starts with 10 liters in the main tank and receives 1 additional liter after 5 liters are consumed, allowing it to use 11 liters total and travel 110 kilometers.

Input: mainTank = 4-int, additionalTank = 100-int
Output: 40-int
Explanation: The main tank contains only 4 liters, so not enough fuel is consumed to trigger a transfer from the additional tank. The truck travels 40 kilometers.

Input: mainTank = 9-int, additionalTank = 3-int
Output: 110-int
Explanation: After consuming 5 liters, 1 liter is transferred from the additional tank. The truck then consumes the remaining 5 liters and receives another 1 liter, using 11 liters total to travel 110 kilometers.

Input: mainTank = 20-int, additionalTank = 4-int
Output: 240-int
Explanation: The truck receives 1 liter from the additional tank after each 5 liters consumed from the main tank, using all 4 additional liters. It consumes 24 liters total and travels 240 kilometers.
