For the answer to the question above, 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 Then If you convert the bison's speed to mph you get that it can run at speeds up to 40 mph.
I got this by seeing how many feet that they run in one hour so 3520 x 60 is 211200 which divided by 5280 is 40 mph.
