Answer 2

Calculating the Time to Fill the Aquarium

To calculate the time it takes for the first pipe to fill the aquarium, we can use the concept of work rates. Let's denote the time it takes for the first pipe to fill the aquarium as x hours and the time it takes for the second pipe to fill the aquarium as y hours.

We are given that the second pipe takes 3 hours to fill the aquarium. Additionally, we know that the first pipe takes 2.5 hours less than the second pipe to fill the aquarium.

Using the Work Rates Concept

We can set up the following equation based on the work rates concept:

1/x - 1/y = 1/3 (as the first pipe takes 2.5 hours less than the second pipe, we can represent this as 1/x - 1/y)

Solving for the Time Taken by the First Pipe

We can solve the equation to find the value of x, which represents the time taken by the first pipe to fill the aquarium.

Let's calculate the value of x using the given information and the equation above.
