You can put this solution on YOUR website! Let = time in hrs for Jim's hose alone to fill pool = time in hrs for Bob's hose alone to fill pool
------
Add their rates of filling to get rate filling together
Multiply both sides by
40.5 = time in hrs for Jim's hose alone to fill pool
32.4 = time in hrs for Bob's hose alone to fill pool
check:
OK
