- <em>It takes</em><u> 2.5 minutes </u><em>to fill the tank.</em>
Explanation:
The net speed or net rate for filling the 10-liters tank is equal to the speed the tap is filling less the speed the water is leaking through the hole located at the bottom of the tank:
- Net rate = rate of filling - rate of leaking
- Net rate = 5 liters/minute - 1 liter/minute
- Net rate = 4 liters/minute
Thus, consiedering the tank is empty at the beginning, the time is:
- Time = Volume of the tank / net rate of filling
- Time = 10 liters / (4liters/minute)
- Time = 2.5 minutes ← answer

Answer:
So the answer should be 1/4.
Step-by-step explanation:
so a cube has all equal sides and volume is equal to s^3 or side*side*side in this case 1/2*1/2*1/2. There are two cubes so you would multiply that by two creating 2*1/2*1/2*1/2
Hope this helps :)
