Water drain out from Tap A into 2 containers at 800 cm3 per minute such that the height of water in the 2 containers is the same. The base area of the 2 containers are 500 cm3 and 300 cm3. What will be the height of the water level in the 2 containers after 20 minute?
This question requires a bit of algebra. Also, the student should be able to get the answer by " Guess & Check " method.
Total volume of water from tap A in 20 minutes = 800 x 20 = 16000
Volume of water in 2 containers --> 500 x height + 300 x height = 16000
--> 800 x height = 16000
height = 16000 / 800 = 20cm
