Question: Johnny is out walking his two dogs at night, and his son joins him for the walk. How many legs' worth of organisms are traveling together for this walk?
Answer: As Johnny and his son are humans, and humans walk on two legs, this means that between the two of them there are 2 * 2 = 4 legs' worth of organisms. There are two dogs walking along as well, and since dogs walk on 4 legs this means there are 2 * 4 = 8 legs' worth of organisms. We add these two totals together to find there are 4 + 8 = 12 legs' worth of organisms in total. The answer is 12.
