Answer:
1 hour and 7 minutes 
Explanation:
- set up two equations: 
  = =
   
- cross multiply: 4.42x =294 
- solve for x: 294 ÷ 4.42 = 66.52 or 67 minutes 
The question is asking for hours rather than minutes so...
 - 1 hour is 60 minutes 
67 min - 60 min = 7 min
Therefore, it would take 1 hour and 7 minutes to fill a 294-gallon hot tub.
