1. The problem statement, all variables and given/known data The tortoise challenged the hare to a race in the woods. The fox is the judge and he stood still. The rabbit started the race 6 minutes after the turtle. The fox said that the turtle won the race after 20 minutes and that the hare arrived 1 minute after the hare. But the hare said "That is not true, I arrived one minute before the turtle". In the turtle's clock, It was marking 16 minutes when it crossed the line. 2. Relevant equations What is the velocity of the hare and the tortoise? Could you explain what happened? 3. The attempt at a solution I know the velocities, but this is completely weird for me. How can the winner depend of the referential?
