60 minutes. Take how far it is above ground (20 m) and add it to the absolute value of how far it is below ground (340 m) to get 360 meters, which you divide by the rate of descent (6 m/min) to get 60 minutes.
        
             
        
        
        
Answer:
The answer to your question is:  x = 2.41
Step-by-step explanation:
                                             2x³ = 28
                                              x³ = 28/2
                                              x³ = 14
                                              x = ∛14
                                             x = 2.41 
 
        
             
        
        
        
Hope it helps :) and let me know if you want me to explain why
 
        
             
        
        
        
2n<2
divide both sides by 2 to solve/isolate n
n<1
