The Children's play area at the Community pool holds a total of 3185 gallons of water it takes 2.5 hours to fill the pool with 1

iren [92.7K]

Answer:

650 gallons after 1 hour

Unit rate:650gallons/hour

Step-by-step explanation:

We are given that

Total capacity of pool=3185 gallon

In 2.5 hours water pool fill=1625 gallon

We have to find how many gallons of water fill in the pool after 1 hour and unit rate.

Using unitary method

1625 gallons of water takes time to fill the pool=2.5 hours

1 gallon of water takes time to fill pool= $\frac{2.5}{1625}$ hours

3185 gallon of water takes time to fill the pool= $\frac{2.5}{1625}\times 3185$ hours

3185 gallon of water takes time to fill the pool=4.9 hours

1 hours , water fill in pool = $\frac{1625}{2.5}$ gallons

1 hours , water fill in pool=650 gallons

Unit rate: How many volumes of water fill in 1 hour.

Unit rate= $\frac{1625}{2.5}=650gallons/hour$
