A swimming pool can be filled at the rate of 25 liters per min using a special pump. How many hours will it take to fill up a pool that holds 5,000 liters of water?

Answer: the correct answer is 3 hours and 20 minutes.

Step-by-step explanation:

25 liters per min means that in 1 minute the pool has 25 liters.

So 5000 / 25 = 200 minutes. It means that the pool will have 5000 liters in 200 minutes.

200 minutes are equal to 3 hours and 20 minutes

3 hours*60 minutes + 20 minutes = 180 minutes + 20 minutes = 200 minutes.

Just divide 25/60 times 5000
