Fuja do Goblin [Math Puzzle]

Survive the Hungry Goblin!

Imagine yourself in the middle of a circular lake, surrounded by water. A malevolent creature known as the Goblin waits hungrily at the edge, eager to devour you. However, there is one advantage: the Goblin cannot swim.

But there is an additional obstacle: the water slows you down. While you move at a normal pace, the Goblin is incredibly agile, capable of moving four times faster than you on land.

The question is: can you survive this relentless challenge?

Strategy is crucial. If you can reach the shore before the Goblin catches you in the water, you will be safe. Use all your swimming skills to overcome the speed disadvantage and reach safety before the Goblin reaches you.

Do you have the courage and skills to beat this challenge and escape the terrible Hungry Goblin? The answer will only be revealed once you are in the lake. Good luck!
