A water treatment facility uses two pumps to fill a reservoir. Pump A can fill the reservoir alone in 12 hours, while Pump B can fill it in 18 hours. Due to maintenance costs, Pump A operates at a rate that decreases by 2% per hour, while Pump B operates at a constant rate. After running both pumps for 2 hours, Pump A is shut down. Approximately how many more hours does Pump B need to complete the filling (to the nearest 0.1 hour)?
