2. divide by denominator 
 
        
             
        
        
        
 The answer is c
the rhombus above is formed by 4 triangles
area of one triangle= 9*13.5*0.5=60.75
area of 4 triangles = 4*60.75=243
        
                    
             
        
        
        
Speed = 416 miles / 8hrs = 52 miles per hr.
Distance = Speed * Time = 52 * 22 = 1144miles
