You will have to use the conversions of feet per minute into miles per hour, because all of the answer choices are in miles per hr. So the deer is already in mph.
Lets look at the American Bison at 3520 ft per min. You can write per as a slash mark (/) so that is what I will be using. $$3520(ft/\min)(1\min/60 \sec)(1mi/5280ft)$$ 
that will be your calculator for how fast the American Bison is in mph. We changed the unit feet into miles and minutes into hours. So you can calculate the value above and then find the difference between the speeds and see which one is the correct answer

In 1 minute, bison runs 3520 feet
In 60 minutes, the bison would run
3520*60 feet
211200 feet per hour.
These are equivalent to;
40 miles per hour since 1 mile is equivalent to 5280 feet.
The bison is faster by 10 miles per hour
