While changing a tyre, a motorist accidentally dropped all four wheel nuts into the sewer grate. Just when the man lost all hope to retrieve the nuts and continue on his way, a kid passed by. After hearing the story, the kid gave an advice, which enabled the driver to successfully fit a new tyre and drive to the nearest service station without any more accidents. What was the advice the kid gave to the motorist?
The kid suggested that the man uses one bolt from each of the other three wheels to fix the fourth one.
