The truck traveled 4/13 of the entire path. He has 82.8 km left to drive. How many kilometers has the truck traveled?

It is known that the distance traveled by the truck was 4/13 of the entire path.
Let’s calculate how much of the distance the truck has left to drive:
1 – 4/13 = 13/13 – 4/13 = 9/13.
Let’s calculate the length of the entire path, for this it is necessary to divide the remaining distance by the part, which it is:
82.8 / 9/13 = 82.8 * 13/9 = 119.6 km.
Let’s calculate how many kilometers the part of the path that the truck has already traveled is equal to:
119.6 * 4/13 = 478.4 / 13 = 36.8 km.
Answer: the truck covered 36.8 kilometers.
