John is going to back to that is 18 inches deep he notices that it takes two minutes to fill the bathtub with 3 inches of water
algol13
Yes,

Every 2 minutes = 3 inches of water, so that means every minute = 1.5 inches of water.

So in 10 minutes:

10*(1.5) = 15 inches of water.

So in 10 minutes the tub will fill an additional 15 inches of water which is exactly how much you need to fill up the remaining tub (3+15 = 18)
