One mile equals 5,280 feet, therefore you would multiply 12 x 5,280 which is 63360 feet per hour.
        
             
        
        
        
Wouldn't it be answer b)?
        
             
        
        
        
1,580 Hectoliters =
1,580,000 Deciliters
        
                    
             
        
        
        
I beleive that it would be C=n25
