J represents Jim's hose's time

12 / J + 12 / (0.30)J = 1

Can you solve for J and answer?

asked • 09/19/17Next-door neighbors Bob and Jim use hoses from both houses to fill Bob's swimming pool. They know that it takes 12 h using both hoses. They also know that Bob's hose, used alone, takes 70% less time than Jim's hose alone. How much time is required to fill the pool by each hose alone?
