Calculating the Time to Fill the Pool Using Two Taps

To calculate the time it takes to fill the pool using both taps simultaneously, we can use the concept of work done. The rate of work done by each tap is inversely proportional to the time it takes to fill the pool.

- The first tap fills the pool in 54 minutes. - The second tap fills the pool in 27 minutes.

To find the combined rate of work for both taps, we can use the formula:

Combined Rate = 1 / (1st Tap Time) + 1 / (2nd Tap Time)

Substituting the given tap times:

Combined Rate = 1 / 54 + 1 / 27

Calculating the combined rate:

Combined Rate = 1/54 + 1/27 = 3/54 = 1/18

Now, to find the time it takes to fill the pool using both taps, we can use the formula:

Time = 1 / Combined Rate

Substituting the combined rate:

Time = 1 / (1/18) = 18 minutes

Therefore, if both taps are used simultaneously, the pool will be filled in 18 minutes.
