a water tank will hold 100 gallons. what flow rate, in gallons per second , is required to fill the tank in 40 seconds
+130020 100/40 gallons per second = 5/2 gallons per second = 2.5 gallons per second
+1667 There are 100 gallons, and to fill the tank up, we need to find the rate of increase in 40 seconds.
Let's divide 100 gallons over 40 seconds.
100/40=2.5
That means that the increase must be 2.5 gallons/second for the 100 gallon tank to be full in 40 seconds.
