Chapter 3

(a) Substitution: 100 hours = 100 · (1/24 of a day) = 41/6 days (b) Conversion Principle: We are converting from a smaller unit (hours) to a larger unit (days), so divide by the conversion factor of 24. Example 3: Suppose it takes you one hour and 20 minutes to run a 10 mile race. ................
