3,500 km 
Step-by-step explanation:
Assuming that 1:500000 is meters you would have to convert to kilometers.
7 * 500000 / 1000 = 3500
 
        
             
        
        
        
4+5 would be 9 because you add 4 and 5
        
                    
             
        
        
        
5+23= 28 .........................
