A leaking pond looses 18 gallons of water in 34 hours , how many gallons will be left after 41 hours
Ann [662]

The amount of water left = 21.3 gallons.

We have a leaking pond which looses 18 gallons of water in 34 hour.

We have to determine how many gallons of water will be left after 41 hours.

<h3>What do you understand by gallon?</h3>

The gallon is a unit of volume in imperial units and United States customary units.

I gallon = 231 cubic inches = 3.785411784 liters.

According to question, we have -

Amount of water lost by the pond in 34 hours = 18 gallons

Therefore -

Amount of water lost by the pond in 1 hour = \frac{18}{34}

So, the amount of water loosed by the pond in 41 hours = \frac{18}{34}\times 41  = 21.3

Hence, the amount of water left = 21.3 gallons.
