Answer:
Maria solved 0.5 (half) of a problem in 1 min
Step-by-step explanation:
Set up proportion and cross multiply to solve:
15 problems/30 min = x/1 min
x = 0.5
1 cubic foot = 7.48 gallons
hence
![\frac{7.48 gal}{1 ft^3} =1](https://tex.z-dn.net/?f=%5Cfrac%7B7.48%20gal%7D%7B1%20ft%5E3%7D%20%3D1)
unit conversion
![\frac{3000 ft^3}{} \times \frac{7.48 gal}{1 ft^3} = 3000 \times 7.48 gal](https://tex.z-dn.net/?f=%5Cfrac%7B3000%20ft%5E3%7D%7B%7D%20%5Ctimes%20%5Cfrac%7B7.48%20gal%7D%7B1%20ft%5E3%7D%20%3D%20%203000%20%5Ctimes%207.48%20gal)
3000 x 7.48 =22440
