Answer:
23.7m
Step-by-step explanation:
Given parameters: 
        Time taken = 2.2s 
      Acceleration due to gravity = 10m/s 
Unknown: 
Depth of the well  = ? 
Solution: 
To solve this problem, we simply apply one of the motion equations;
         S = ut +  gt²
 gt²
     where S = depth of the well 
                 u = initial velocity 
                 t = time taken 
                g = acceleration due to gravity
  Input the parameters and solve for S;
    Note initial velocity = 0;
      S =  x 9.8 x 2.2²
 x 9.8 x 2.2²
      S = 23.7m
