Question

Amin is using a hose to fill his new swimming pool for the first time. He starts the hose at 10 PM and leaves it running all night. At 10 AM he measures and finds the pool is still only 3 quarters full. When will the pool be full?

Answer 1

Answer: 2PM

Explanation:

We can use train tracks. But first, remember that 10 PM to 10 AM is 12 h.

`1cap.*(12h)/((3)/(4)cap. ) \\ =12h*1cap.*(4)/(3cap.) \\ =16h`

The pool will be full after 16h. 12 h have and it is now 10 AM, so after 4 h after hours 16 h will have past. Also, after 4h it will be 2 PM.
