Suppose that a given road has a maximum load of 20 tons per axle on a given vehicle. Suppose a truck has 16 wheels, with four wheels per axle, and weighs 14 tons. What is the maximum weight in kilograms that this truck can carry on a given road?


Let `x` is maximum number of weight in kilograms that truck can carry, then it can carry `x/1000` tons.

Since truck weighs 14 tons then its maximum weight is `x/1000+14`.

From another side each axle can handle 20 tons and since there are `16/4=4` axles then maximum weight truck can carry is `20*4`.



Solving this we obtain that `x/1000=66` or `x=66000`.

Answer, truck can carry 66000 kilograms.
