Question

My filter cleans 125 gallons every hour. How many times does my 20 gallon tank get cleaned every hour

Answer 1

6.25 times (6.25 times mean the filter cleans the 20 gallon capacity tank 6 times for fully, and the $7^{th}$ time the filter cleans only 5 gallons) of 20 gallon tank get cleaned, if the filter cleans 125 gallons for every hour.

Step-by-step explanation:

The given is,

                 Filter cleans 125 gallons every hour

                 How many times 20 gallon tank get cleaned every hour

Step:1

               Formula for number times 20 gallon tank get cleaned is,

                                 $No.of times, n= \frac{Filter clean capacity per hour}{Capacity of tank}$...........(1)

             From the given values,

                   Filter clean capacity per hour = 125 gallons per hour

                                         Capacity of tank = 20 gallons

             Equation (1) becomes,

                                            $n = \frac{125}{20}$

                                               $= 6.25$

                                            n = 6.25 times

             Number times 20 gallon tank get cleaned, n = 6.25 times

             Where, 6.25 times mean the filter cleans the 20 gallon capacity tank 6 times for fully, and the $7^{th}$ time the filter cleans only 5 gallons.  

Result:

            6.25 times of 20 gallon tank get cleaned, if the filter cleans 125 gallons for every hour.
