The baxters, the gillberts, and the Sings are pumping water into the swimming pool in their city park. The pool will hold 302000 gallons of water. These neighbors are using their garden hoses to fill up the pool. The Gilberts' hose pumps 92 gallons for every 12 gallons pumped by the Baxters' hose. The Sings' hose pumps 85 gallons of water per hour. How many hours will it take the three neighbors to fill the pool, and how much water will each of them have pumped into the pool? show your work

Do the families have the proper permits to add water to the public pool? If not should the time to acquire the permits be considered ?
Secondly, What is the temperature of the water coming out of the hoses, as cooler water will expand and fill the pool faster.

Considering all of the unknowns we can not solve for Time. Do you know how much water the Baxters are delivering to the pool? It appears they did not pay their Water bill.

Pool=302,000
Gilberts=G=(B/12)*92/H
Baxters=B
Sings=S=85gallons/H

Time=302,000/S+B+G/H
