This problem is a simple dimensional analysis. We are simply tasked to express the rate 0.992 atm/m to atm/km.
Dimensional analysis, in simpler terms, is just the process of expressing an answer in another unit by multiplying conversion factors.
For this problem, we'll need to perform the following:
Notice that we used the conversion factor 1000 meters = 1 kilometer to convert the units from atm/m to atm/km. Thus, we arrive at the final answer 992 atm/km.
