Question

A tank is filled with water up to a height of 10 meters. The tap at the top is opened, and water is filled in the tank at the rate of 3 meters per minute for 1/2 hour. Then the tap at the top is closed. After 5 minutes, the tap at the bottom of the tank is opened, and water is drained out at the rate of 5 meters per minute till the tank is completely empty. Does this represent direct variation?

a) Yes
b) No

Answer 1

No, the situation does not represent direct variation.

Step-by-step explanation:

In this problem, we are given the dimensions of a tank that is filled with water. We are also given the rates at which water is filled and drained from the tank. The question asks if this situation represents direct variation.

Direct variation occurs when two quantities increase or decrease at the same rate. In this case, the rate at which water is filled and drained from the tank is different, so it does not represent direct variation.

Therefore, the answer is b) No.
