How many metres must the jack be from the mat line after being centered?

The correct answer is based on the regulations that govern the placement of the jack in a game of bowls. After the jack has been centered, it must be positioned a minimum distance from the mat line to ensure fair play and to maintain the integrity of the game. According to the rules, the jack must be at least 23 metres away from the mat line. This distance is significant because it ensures that players have enough space to bowl effectively while also maintaining the challenge of the game.

The rationale behind setting this minimum distance is to create a standard playing format that all participants must adhere to, contributing to consistency in the sport. Understanding these requirements is essential for umpires to enforce the rules properly and for players to be aware of the necessary parameters during play.
