Answer: The microbes only grew in the bottles containing earth-like air.
Explanation:
The growth of microbe depends upon the availability of substrate, moisture, and gas. The atmosphere is a mixture of gases. Earth-like atmosphere favors the survival of many micro-organisms. Carbon dioxide, oxygen, methane, nitrogen, and others are valuable earth like gases that will favor the survival of many microorganisms.

Answer:
8.6 km/hr

It looks like there's a lot of extra information here. If the question only asks about the trip from Rohn to Nikolai, then the only information that matters is that the distance between the two is 121 km & that Seavey did it in 14 hours. Don't let the extra numbers throw you off.
As for the math behind this - km/hr is a math equation in and of itself. Any ratio like that is a simple division problem. Just plug your numbers (121 km / 14 hr) into the formula (km / hr) to get your answer!
EDIT: for future questions where they don't label it as clearly... velocity = the distance divided by the time.
