Hi,
A is an arithmetic sequence 
U(n)=U(n-1)+3
        
             
        
        
        
Answer:
 67.5feet
Step-by-step explanation:
Given parameters: 
Model distance between building and gymnasium  = 22.5 inches
Scale of model :  1 inch  = 3 feet
Unknown: 
Actual ground distance  = ? 
To solve this problem, we first must understand the concept of scale. A scale is a relationship that represents a dimension on a map/model compared to the true ground expression. In order to visualize or represent some real life objects on paper or in a computer, we use models. These models are an abstraction of the real world based on scales. There are different ways of representing a scale.
In this problem; 
     the scale is given as; 
                      1 inch on model  represents 3 feet on ground
Now, to find 22.5 inches, simply cross multiply and solve; 
         If   1 inch on model  represents 3 feet on ground
               22.5 inches on a model  will be =  
                                                                    = 67.5feet 
 
Therefore, the actual distance is 67.5feet
 
        
             
        
        
        

Actually Welcome to the Concept of the Inequalities.
so we get as,
(w+6)/2 < 5
so we get as, 
w+6 < 10 
=> w < 10-6
=> w < 4
so the answer is, 
w < 4
