Question

A container holds 80,000 ounces of water. There is a small leak in the the container. Every 96 minutes, 1.9 ounces of water leak out. What is the total change in water after 8 hours?

Answer 1

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 * (1 hour)/(60minutes)=(96)/(60)=1.6hours\\`

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:

`(8hours)/(1.6hours)*1.9 = 9.5\\` 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:

`80 000-9.5=79990.5` ounces
