Hi Iyanna,
First determine the time in minutes. Since we know that for every minute 3.73 gallons would be added to the tub, we can divide 335 by 3.73 to find the number of minutes:
335 ÷ 3.73 = 89.812 minutes
Recall that 60 minutes is equal to 1 hour .
Then 89.812 minutes ÷ 60 = 1.497 hours or approximately 1.5 hours to fill the tub
