Ahose fills a hot tub at a rate of 2.87 gallons per minute. how many hours will it take to fill a 328-gallon hot tub?

1.90 hours

Step-by-step explanation:

We need to first find the unit rate, the number of minutes taken to fill 1 gallon.

It is given, 2.87 gallons per 1 minute, to get "how long" it will take to fill up 1 gallon, we have to divide the number of minutes (1) by the number of gallons (2.87).

So,

1/2.87 = 0.3484 minutes per gallon

Now, we need the time it will take to fill 328 gallons. We simply multiply 328 by the unit rate found (0.3484). We have:

328 * 0.3484 = 114.2857 minutes

We need the answer in hours, so we divide by 60:

114.2857/60 = 1.90 hours
