Answer: 
4h=p
Step-by-step explanation: 
This is the answer because if both the number of trees and hours is divided by three, you get 4 trees per hour. So it's 4 times (h) equals total amount of trees planted.
 
                                
             
                    
              
Answer:  
Step-by-step explanation: 
The given statement:  Wangari plants trees at a constant rate of 12 trees every 3 hours.
Using unitary method, the number of tree planted by Wangari in every hour : 
i.e. Wangari plants trees at a constant rate of 4 trees every hour.
Let the number of trees planted by Wangari be 'p'and h, the time she spends planting them in hours.
Then, equation that relates p and h will be:
