Answer:
45.04 cm
Explanation:
The tired physics professor red easily at a distance of 26 cm
So v = 26 cm
And it is given that object distance that is u = 61.5 cm
There is relation between focal length object distance and image distance that is 
Here f =focal distance v = image distance and u = object distance
So 
So f=45.04 cm
Ok let me help you with this:

!n case a) Line both up head-to-tail in a straight line... that's the only way to get a sum 2F. In case b) sqrt(2) is the length of the hypotenuse in a 45 degree triangle, so the vectors must be at 90 degrees to each other
in the case of c) lined up head to tail, the only way to get 0 is if they point in opposite direction</span>
