Answer:
Focal Length = 38.61cm, Power = 2.59 Diopter, Converging lens.
Explanation:
When an object is placed 25cm from Gbenga's eye, the glasses lens must produce an image 61cm away (Gbenga's eye near point).
An image 61cm from the eye will be (61cm - 1.6cm) from the glasses.
i.e. 
and 
note 
will be negative because the image is formed on the same side as the object.
finally, 
the formula for finding the focal length 
is given as
The focal length is positive which indicates converging lens
power 
but 
must be in metres
Therefore,
