Question Analysis

The question asks for the portion of the tank that can be filled by each pipe in one hour. We are given that the first pipe can fill the tank in 2 hours and the second pipe can fill it in 3 hours.

Answer

To find the portion of the tank that can be filled by each pipe in one hour, we need to calculate the rate at which each pipe fills the tank.

Let's assume that the capacity of the tank is 1 unit.

The first pipe can fill the tank in 2 hours, so its filling rate is 1/2 units per hour.

The second pipe can fill the tank in 3 hours, so its filling rate is 1/3 units per hour.

Therefore, the first pipe can fill 1/2 of the tank in one hour, and the second pipe can fill 1/3 of the tank in one hour.

Detailed Calculation

Let's calculate the filling rates of each pipe:

- The first pipe can fill the tank in 2 hours, so its filling rate is 1/2 units per hour. - The second pipe can fill the tank in 3 hours, so its filling rate is 1/3 units per hour.

Therefore, in one hour:

- The first pipe can fill 1/2 of the tank. - The second pipe can fill 1/3 of the tank.

Conclusion

In summary, the first pipe can fill 1/2 of the tank in one hour, and the second pipe can fill 1/3 of the tank in one hour.
