Hint: Try this with a coin.
Answer: 4 feet.
If we consider the logs on their own for a moment, for each full turn, they will travel 2 feet (in relation to the floor).
However, at the same time, the block on top will also travel 2 feet (in relation to the logs).
For a total movement of 4 feet for the block on top.
Which fruit comes next in this sequence:

Hint: 28,121 isn't a prime number.
Answer: 61 bags.
Each containing 461 carrots. If you think that one big bag will suffice, then feel free to calculate its size and then email me!
How do we find the correct answer? An easy way is to keep dividing 28,121 by the prime numbers in sequence until one works.
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61.
How should these words actually be spelled - without using a dictionary.
