Answer 3

To solve this problem, we need to calculate the amount of water that will be in the empty reservoir after 5 hours.

Step 1: Calculate the total amount of water poured into the reservoir in 5 hours

First, we need to calculate the total amount of water poured into the reservoir in 5 hours.

The water is pouring into the reservoir through two pipes. One pipe pours water at a rate of 50 liters per minute, and the other pipe pours water at a rate of 30 liters per minute.

To calculate the total amount of water poured into the reservoir in 5 hours, we need to find the total amount of water poured by each pipe and then add them together.

The first pipe pours water at a rate of 50 liters per minute. So, in 1 hour (60 minutes), it will pour 50 liters * 60 minutes = 3000 liters of water. Therefore, in 5 hours, the first pipe will pour 3000 liters/hour * 5 hours = 15000 liters of water.

The second pipe pours water at a rate of 30 liters per minute. So, in 1 hour (60 minutes), it will pour 30 liters * 60 minutes = 1800 liters of water. Therefore, in 5 hours, the second pipe will pour 1800 liters/hour * 5 hours = 9000 liters of water.

Adding the amounts of water poured by each pipe, we get a total of 15000 liters + 9000 liters = 24000 liters of water poured into the reservoir in 5 hours.

Step 2: Calculate the amount of water remaining in the reservoir

To calculate the amount of water remaining in the reservoir after 5 hours, we need to subtract the amount of water poured into the reservoir from the initial capacity of the reservoir.

However, the initial capacity of the reservoir is not provided in the question. Without this information, it is not possible to determine the amount of water remaining in the reservoir after 5 hours.

Please provide the initial capacity of the reservoir, and I will be able to help you further with the calculation.
