Calculation: Your company plans to transport 20 horses to a racetrack in Denver. It takes 12 hours to drive from Phoenix to Denver. You have to stop and feed the horses every 2 hours. You also need a 6 hour sleep for every 10 hour drive. What would your critical ratio be if you only had 2 days left to meet your deadline and you only have to consider feeding the horses and taking your required amount of nap? Please show all work and explain deviations.
