Question

the elephants water tank holds 2560 gallons of water. Afterbtwo weeks the zookeeper measures and finds that the tank has 1944bgallons of water left. If the elephant drinksbthebsame amount of water each day how many days will a full tank of water last

Answer 1

2560-1944= 616gallons
7 days in a week or 14 days in two weeks
616gallons / 14days = 44 gallons / 1 day
Notice in the fraction we have
(Gallons / days)
Now if you filled the take up the entire way
2560 gallons
We have gallons and the question wants the amount of days
Thus to cancel gallons we set the equation up as such
(2560 gallons) x (1 day / 44 gallons) = 58.18 days
Or 58 days

Answer 2

The full tanks of water will last for 58 days

Further Explanation

Given:

The full tank of water = 2560 gallons

After 2 weeks ⇒ water left 1944 gallons

Elephant drink the same amount of water each day

Question:

How many days will a full tank of water last?

First step, we are going to find the amount of water drink by elephant each day:

= Full tank of water - water after two week

                        14 days

$\boxed {\frac{2560-1944}{14} = \frac{616}{14} = 44 }$

So each day the elephant drinks 44 gallons of water

Full tank of water = 2560 gallons, so it would be last for:

$\boxed {\frac{2560}{44}= 58.18 }$ days or rounding to 58 days

Full tank of water will last for 58 days.
