Answer 2

Calculating Pumping Rates for Two Pumps

To solve this problem, we can use the concept of simultaneous equations. Let's denote the rate at which the second pump can pump water as x units per hour. Since the first pump takes 3 hours longer than the second pump, its rate can be represented as (x - 3) units per hour.

Given that both pumps working together can pump the water out of the pit in 3 hours and 36 minutes, we can convert this time to hours. 36 minutes is equal to 0.6 hours, so the combined rate of both pumps is the reciprocal of the time taken: 1 / (3.6)

Now, we can set up the equation: 1 / (3.6) = 1 / (x) + 1 / (x - 3)

Let's solve for x to find the rate at which each pump can pump water.

Solving the Equation

Using the equation 1 / (3.6) = 1 / (x) + 1 / (x - 3), we can solve for x to find the rate at which each pump can pump water.

Calculating the Pumping Time for Each Pump

Once we have the value of x, we can calculate the pumping time for each pump. The pumping time for each pump is the reciprocal of its pumping rate.

Let's proceed with solving the equation and calculating the pumping time for each pump.
