Pump A can fill a tank in 8 hours. Pump B can fill the tank in 6 hours. How long will it

take to fill the tank using both pumps? Round answers to the nearest tenth if

necessary.

3.43 hours

Step-by-step explanation:

For every hour, Pump A can fill 1/8 tank and pump B can fill 1/6 tank.

For every hour, both pump A and pump B can fill:

1/8 + 1/6 = 14/48 = 7/24 (tank)

It will take: 1 : 7/24 = 24/7 ≈ 3.43 (hours)
