PLZ HELP ASAP One pump fills a tank 4 times as fast as another pump. If the pumps work​ together, they fill the tank in 20 minutes. How long does it take for the faster pump to fill the​ tank?

It takes the faster pump 12 minutes to fill the tank.

Since the faster truck can produce 60% more than the other truck. 60% of 20 minutes is 12.
