Respuesta :
The tank fills up at a daily rate of
(6 gal/hr) (24 hr/day) = 144 gal/day
so the net rate is
144 gal/day - 69 gal/day = 75 gal/day
and after 24 hours, the tank would contain 75 gal of water.
75 gallons of water would be in the tank after 24 hours.
How to elaborate the problem ?
Tank A fills at a rate of 6 gallons/hr
We know that, 1 day = 24 hours
So, Tank A fills in a day = (6 × 24) gallons
Given that, The tank discharge water at a rate 69 gallons per day.
How much water would left after 24 hours ?
Total water in the tank A in 24 hours = 144 gallons
Tank A discharge water in 24 hours = 69 gallons
∴ Water left in the tank A after 24 hours = (144-69) gallons
= 75 gallons
