Water flows from a pipe at a rate of 3,2 litres/minute.how long will it take to fill a 2,8 kilometre tank?give answer in hours and minutes.
Did you mean a 2.8 kilolitre tank?
I have not idea what a 2.8 km tank is.
I hour 28min
To find the time it takes to fill the tank, we first need to convert the tank volume from kilometers to liters.
1 kilometer is equal to 1000 meters, and 1 meter cubed is equal to 1000 liters. So, we can calculate the tank volume in liters:
Tank volume = 2.8 kilometers * 1000 meters/kilometer * 1000 liters/meter cubed = 2,800,000 liters
Now, we know that the rate of water flow is 3.2 liters per minute. We can set up a proportion to find the time it takes to fill the tank:
3.2 liters/minute = 2,800,000 liters/x minutes
To solve for x, we can cross-multiply:
3.2x = 2,800,000
Divide both sides of the equation by 3.2 to isolate x:
x = 2,800,000 / 3.2 ≈ 875,000
So, it will take approximately 875,000 minutes to fill the tank.
To convert the answer to hours and minutes, we divide the total minutes by 60 to get the number of hours, and the remainder will be the minutes.
875,000 minutes ÷ 60 minutes/hour = 14,583.33 hours
Since we want the answer in hours and minutes, we round down the number of hours to 14 and calculate the remaining minutes:
Minutes = (14,583.33 - 14 hours) * 60 minutes/hour = 50 minutes
Therefore, it will take approximately 14 hours and 50 minutes to fill the tank.
