It is known that 60 minutes equals 1 hour.
Therefore, the first thing we do to solve the problem is to calculate how many hours are equivalent to 96 minutes.
For that we calculate:
![96 minutes * \frac{1 hour}{60minutes}=\frac{96}{60}=1.6hours\\](https://tex.z-dn.net/?f=96%20minutes%20%2A%20%5Cfrac%7B1%20hour%7D%7B60minutes%7D%3D%5Cfrac%7B96%7D%7B60%7D%3D1.6hours%5C%5C)
Thus:
96 minutes = 1.6 hours.
1.9 ounces of water are lost every 1.6 hours.
Therefore, in 8 hours the amount of water lost is:
ounces of water
After 8 hours, 9.5 ounces of water are lost
Therefore, the amount of water left in the tank after 8 hours is:
ounces
