Question

Gwen is filling a pool. She begins to wonder how fast the water is flowing into the pool. Which unit rates would be reasonable for Gwen to use to describe how fast the pool is filling with water? Select each correct answer. gal/h cm3/min L/h in3/s

Answer 1

Gallons per hour & liters per hour

Answer 2

I just took the test and the answer was  gal/h and L/h, the reason it's not cm3/min or in3/s is because you can't measure water using centimeters or inches.. But you can measure water with Gallons and Liters :)
