Answer:
1.25 focal lengths
Explanation:
The lens equation states that:

where
f is the focal length
p is the object distance
q is the image distance
In this problem, the image is 4 times as far from the lens as is the object: this means that

If we substitute this into the lens equation and we rearrange it, we get

so, the object distance measured in focal lengths is
1.25 focal lenghts
