Solve the following question given below:

Question: At what distance will a 55W light bulb have the same apparent brightness as a 120W bulb viewed from a distance of 45m? (Assume that both bulbs convert electrical power to light with the same efficiency, and radiate light uniformly in all directions.)

I need tutor help to solve the above question and express your answer using two significant figures.
