From the linked article:
"Grizzly bears chased by trucks have been clocked doing 35 mph. That's 3,080 feet per minute or 102 feet per second. At that speed, it would take a bear about a fifth of second -- 200 milliseconds -- to cover 20 feet. " For the record: 35 mph = 3,080 ft/min = 51 ft/sec
So, it would take two fifths of a second to cover 20 feet. Still not a lot of time to take careful aim. But plenty of time to consider taking up a different hobby.
Deep breaths, focus on target, slowly squeeze the trigger.. Yeah, right!
