Question

an 18000 gallon pool takes approximately 40 hours to fill. what is this rate in pints per minute?
Ms. Sue
It's your turn now. Use your conversions list.
sahsa
18000 gallons
40 hours


i don't know the rest
Ms. Sue
How many pints in a gallon?

How many minutes in 40 hours?

sahsa
8 pints
2400 minutes
Reiny
I would do it this way:

18000 gallons in 40 hrs
= 450 gallons/hr ---- divide by 40
= 3600 pints/hr ----- there are 8 pints in a gallon
= (3600/60) pints/min ---- there are 60 min in 1 hr
= 60 pints/min

or the way Ms Sue suggested

18000 gal = 144000 pints
40 hrs = 2400 minutes, so

18000 gal per 40 hrs
= 144000 pints per 2400 minutes
= (144000/2400) pints/min
= 60 pints/min
sahsa
can you pleaSE put it in the chart format so that i can understand it better
Reiny
I am not familiar with the "chart format" your teacher is using.
I solved it the way I used to teach this kind of problem.
sahsa to reiny
like you see.

18000 gallons
40 hours


then beside that u use the conversions that get from gallons to pint per min . then u cross out the labels that u have in common multiply then divode
Reiny
you mean something like this ..... ???

18000 gallons ---- 144000 pints
40 hours ------ 2400 minutes ----(144000/2400) pint/min
to get 60 pints/min

If you look above that is exactly what I did
just fill in the places in your "chart"
sahsa to reiny
look at my last example on how to do the chart
