Riddle
If you're 8 feet away from a door and with each move you advance half the distance to the door. How many moves will it take to reach the door?
Choose an answer
A.Eight
B.Four
C.Sixteen
D.Infinity! Technically you will never reach the door, as you can only move half the distance, no matter how small.
Hint: It's a 20-word phrase with 90 letters, starting with "I".
Answer
Infinity! Technically you will never reach the door, as you can only move half the distance, no matter how small.
Why this is the answer
Since each move only closes half the remaining gap, an infinitely small distance always remains - a classic illustration of Zeno's paradox of motion.
