Answer:
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
