OMG.  This is not difficult.

Think of it in terms of 24 gallon units.  How many 24 gallon units are in 139 gallons?  Divide 139 by 24.  There are in round numbers, about 5.8 twenty-four gallon units.

Each 24 gallon units takes 5 minutes to drain.  So multiply 5.8 units by 5 minutes per unit and you about 29 minutes.  Rounding it to 30 minutes and you have half an hour.  For exact numbers, your calculator should work as good as mine.

I got 4.8 hrs like lady4u.

For every 5 mins the tub drains 24 gals of water. So in 10 mins it will drain 48 gals of water.  Multiply that 10 by 6, to make it an hour, and multiply the 48 by 6 as well, you get 288 gals. Divide that by 60, and its 4.8.

Well I was wrong. That was for 288 gals.   It would take about 28 mins.  I made a table.  !!

Divide 24 by 5 to get the amount of gallons per minute = the tub drains at 4.8  gallons per minute

Divide 139 by 4.8 to get the amount of minutes to drain the tub = 28.95833333333333

Therefore it will take less than an hour to drain.
