A tank contains 1200 litres . A tap is turned on and 40 litres of water escape each minute. How much water has escaped in 12 minutes.
ummm, 40*12, don't you think?
The capacity of the tank does not make any difference.
To find out how much water has escaped in 12 minutes from a tank that initially contains 1200 liters and has a tap releasing 40 liters per minute, you can use the formula:
Amount of water escaped = Rate of water escaping × Time
In this case, the rate of water escaping is given as 40 liters per minute, and the time is 12 minutes.
So, the amount of water that has escaped in 12 minutes can be calculated as:
Amount of water escaped = 40 liters/minute × 12 minutes
Let's now calculate it step by step:
40 liters/minute × 12 minutes = 480 liters
Therefore, 480 liters of water have escaped from the tank in 12 minutes.
