### Grade 3 - Mathematics7.4 Working With Time Through Noon or Midnight

 Method: 4:30 is also read as half past 4. (because 30 minutes makes half an hour) 4:15 is also read as quarter past 4. (because 15 minutes makes quarter hour) The elapsed time is the difference between two intervals of time. Example: Students take 45 minutes to complete the test. The test started at 3.45 pm. At what time will they complete? Start time = 3:45 End time = 3:45 + 45 = 4.30 (3:45 to 4:45 is 1 hour, that is 60 minutes, since its 45 minutes subtract 15 from 4:45) Answer: 4.30 pm Directions: Answer the following questions. Also write at least 10 examples of your own.
