To find out how many tanks are filled in .71 hours, set up the left side of the equation shown above, and multiple by .71 Then add the numbers in the parenthesis and multiple by .71 Change the .7455 to a fraction to get the answer
To figure out how long it takes to fill exactly one tank set the right side of the equation, which represents the number of tanks filled, to one. Set the number you are multiplying the (1+.25-.2) to X. X is the number of hours. Add the numbers inside the parenthesis again. Divide both sides by 1.05 Set the .952 over 1 and X over 60 to get the amount of times in minutes
Cross multiple and Z=57.14 minutes. The final answers are therefore The tank becomes Of the way filled in .71 hours. And it take 57.14 minutes to fill the entire tank
