answer: 7 minutes
I came here to find the answer to this proble but since no one answered I’ll just put the answer that I got.
Step-by-step explanation:
 
        
             
        
        
        
If its going by $11 for 2 hours then he babysat ?
ok so $11= 2 hours 
11 x 3= 33    half of eleven is 5.5 
so 33+ 5.5 = $38.50 so I believe the answer is 6 hours and 30 min but I'm not 100 percent positive
