Answer:
8.6 km/hr
Explanation:
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.
They would be concerned becuase they affect they area with the symptoms/problems and they would aid them because they are most ways common symptoms are found and usually help find more problems
If you mean geographically/biologically - the world is changing, and so will the environment, and with the problems we have now a days, it's likely to change fast in aspects such as temperature (will get hotter), fauna and flora (will decrease), etc.
If you mean politically - some countries might gain more territory trough battles or wars, and some other countries might possible "reclaim" long-lost lands that belong to them historycally.
