Calculation of Chess Game Duration

To determine the duration of the chess game before the break, we can use the information provided that the chess players played for 4/5 of the total time of the game. Additionally, we know that they played for 2 hours before the break.

Let's calculate the duration of the chess game:

1. We can set up the equation: 4/5 * Total Time = 2 hours.

2. To find the total time, we can multiply both sides of the equation by 5/4: Total Time = (2 hours) * (5/4).

3. Simplifying the equation, we get: Total Time = 2.5 hours.

Therefore, the chess game lasted for 2.5 hours before the break.
