Answer:
B?
Step-by-step explanation:
I think is B because solar power never run out.
(For the next 5000000000 years at least...)
 
        
                    
             
        
        
        
I'd suggest you write "6 2/5," not "6 and 2/5."
6 2/5 rotations
-------------------- = 
2 2/3 seconds
32
---
 5            32       3
------- = ------ * -----
 8              5       8                 Reduce that 32/8:  obtain 4.
---
 3
Then we have
4(3)/5, or 12/5 rotations per sec.
        
             
        
        
        
85 + 91 + x ÷3 ≥94
You didn't give any choices but this represents the problem.
