Answer:
   35 minutes
Step-by-step explanation:
The total amount of water is 200 +60 = 260 gallons. The two tanks will have equal amounts when each has half that, or 130 gallons.
If the volume in tank 2 is increasing at 2 gallons per minute, it will increase by 70 gallons from 60 gallons to 130 gallons in 70/2 = 35 minutes.
 
        
             
        
        
        
A(n)=a(1)+d(n-1),    d=a(16)-a(15)=-5-(-53)=48
a(15)=a(1)+d*(15-1),  
-53=a(1)+48*(15-1),
a(1)=-53-48*14= -725
a(n)=-725+48(n-1)
