Answer:
   11 73/78 ≈ 11.9359   (not 14)
Step-by-step explanation:
The similarity statement tells us ...
   QS/QR = FG/FH
   QS = QR·FG/FH
   13x -14 = 154(55/60) = 847/6
Adding 14 = 84/6, we have ...
   13x = 931/6
   x = 931/78 = 11 73/78 . . . . . . . divide by 13

<em>Comment on the question</em>
You get a nice integer answer for x if the similarity statement is written ...
   ∆FGH ~ ∆QRS . . . . . . . note the letters are in alphabetical order
Then you have ...
   QS/QR = FH/FG
   13x -14 = 154(60/55) = 168
   13x = 182
   x = 14
This nice answer to a nice similarity statement leads us to believe the question has an error in it.
We suspect you are expected to provide x=14 as the answer, even though that is NOT the answer to the question <em>as written</em>. You may want to discuss this with your teacher.
 
        
             
        
        
        
Distance = rate * time
580 = (80+65) * t 
T = 4 hours
