Petra has 20 min.to finish pumping the water out of the pool. There are 1850 gallons of water left in the pool. Will Petra be finished in 20 min.? Why or why not?

I say no because I multiplied 1850 by 20 and got 37,000. She want be finished in 20 min.

Is this correct

How fast is she pumping the water out of the pool?

Answered by Elle
How fast is she pumping the water? (how many gallons per minute)?

You need that conversion factor (gallons per minute) in order to calculate the time it takes her to pump the 1850 gallons

450 gallons in 5 min.

450 * 4 = 1800 gallons in 20 minutes.

Nope --- she won't be finished in 20 minutes.
