Answer:
The actual length of 60 cm is modeled as 1 cm length.
Step-by-step explanation:
The diameter of the sweep of the main rotor of the helicopter is 18.6 meters i.e. 1860 cm.
Now, the toy model of the helicopter has a sweep of 31 cm.
Therefore, the scale in which the model is made is 1860 : 31 i.e. 60 : 1 ratio.
So, the actual length of 60 cm is modeled as 1 cm length. (Answer) 
 
        
                    
             
        
        
        
13=1+4s 
So you find S
So you take out 1, and subtract 1 from thirteen 
12=4s so then you divide it by 4 
12÷4=3 
s=3
