Calculation: Your Company plans to transport 20 horses to a racetrack in Denver. You know that it takes 12 hours to drive directly from Phoenix to Denver. You also know that you have to stop and feed the horses every 2 hours. You also need a six-hour sleep every 10-hour drive. If you were the logistics operations manager responsible for this move, what would be your critical ratio if you had only 2 days left to meet your deadline and you only have to consider feeding the horses and taking your required amount of nap?
