                    days into hours
                    Rule: To convert days into hours, we multiply the number of days by 24.

                    example 1. Convert the following into hours.                          units of Time Conversion
                                 a.  8 days                    b.  3 days 8 hours
                                                                                                1 day = 24 hours
                    Solution.  a.  8 days = 8 × 24 hours = 192 hours                           1 hour = 60 minutes
                                 b.  3 days 8 hours = 3 days + 8 hours
                                                        = 3 × 24 hours + 8 hours            1 minute = 60 seconds

                                                        = 72 hours + 8 hours = 80 hours

                                                                                                                 191
                                                                                                        Time
