How fast would a zombie-like outbreak take over the world? Let's find out. In a secret govemment facility, a biological weapons test goes homibly wrong, turning 5 test subjects into the
walking dead. Every hour each zombie has managed to bite, and infect, 3 people. Assuming this rate
remains constant for the first 24 hours after the outbreak begins, model and analyze the spread of the
disease.
Use the chart to keep track of the increase in zombies through infection after t hours.
