Answer: 1215 miles
Step-by-step explanation:
405 miles in 5 hours is 81 mph so you multiply that mph by the amount of hours you want (15)  so 81 x 15 = 1215
 
        
             
        
        
        
19.2 * 10⁸ minutes.
60 minutes = 1 hour.
19.2 * 10⁸ minutes =  (19.2 * 10⁸) / 60  hour
                 
                              = 32 000 000 =   3.2 * 10⁷ hours
= <span>D. 3.200 × 10^7 h</span>
        
             
        
        
        
If it is 50% then it should be half of the original price. 
For Example: $30.00 - 50%... the answer would be $15.00 since its the half of the $30.00
