Pinocchio's Nose Growth and Truth-Telling

Pinocchio's nose grows by 3 cm when he lies and shortens by 2 cm when he tells the truth. Over the course of an hour, the length of his nose changed 6 times and increased by 8 cm in total. We can use this information to determine how many times Pinocchio lied.

To solve this problem, we can use a simple equation to represent the changes in the length of Pinocchio's nose.

Let's denote: - L as the initial length of Pinocchio's nose - x as the number of times Pinocchio lied - 6 - x as the number of times Pinocchio told the truth

The equation representing the changes in the length of Pinocchio's nose can be expressed as: L + 3x - 2(6 - x) = L + 8

Solving for x: L + 3x - 12 + 2x = L + 8 5x - 12 = 8 5x = 20 x = 4

So, Pinocchio lied 4 times over the course of an hour.
