An Arab sheikh tells his two sons to race their camels to a distant city to see who will inherit his fortune. The one whose camel is slower will win. The brothers, after wandering aimlessly for days stalling, delaying, and resolving nothing, ask a wise man for advice. After hearing the advice they jump on the camels and race as fast as they can to the city. What does the wise man say?

SOLUTION (hilight to read):

The wise man told them to switch camels.
