Answer:

4.7

Step-by-step explanation:

Given :

initial mean length =4.1  minutes.

Final mean length =5.3 minutes

The mid point of the given interval can be determined by the

Midpoint \ = \frac{Initial\ Mean\ length\ +Final\ Mean\ length }{2}  \\Midpoint \ = \frac{4.1\ +\ 5.3\  }{2}  \\Midpoint \ = \frac{9.4 }{2}  \\Midpoint \ =4.7\\

Therefore 4.7 is the midpoint
