  2. How can I use elapsed time to find start times?

  3. To find the start time: • Count backward the correct number of hours. 2. Count backward the correct number of minutes.

  4. Start Time = ? 6:16 p.m. Elapsed Time = 3 hours 8:16 p.m. 7:16 p.m. 6:16 p.m. End Time = 9:16 p.m.

  5. Start Time = ? 2:24 a.m. Elapsed Time = 5 hours 6:24 a.m. 5:24 a.m. 4:24 a.m. 3:24 a.m. 2:24 a.m. End Time = 7:24 a.m.

  6. Start Time = ? 10:45 a.m. Elapsed Time = 4 hours 1:45 p.m. 12:45 p.m. 11:45 a.m. 10:45 a.m. End Time = 2:45 p.m.

  7. Start Time = ? 4:35 p.m. Elapsed Time = 3 hours, 15 minutes 4:50 6:50 p.m. 5:50 p.m. 4:50 p.m. End Time = 7:50 p.m.

  8. Start Time = ? 9:15 a.m. Elapsed Time = 2 hours, 20 minutes 10:35 a.m. 9:35 a.m. 9:35 End Time = 11:35 a.m.

  9. Start Time = ? 2:40 p.m. Elapsed Time = 3 hours, 20 minutes 3:00 5:00 p.m. 4:00 p.m. 3:00 p.m. End Time = 6:00 p.m.

  10. Start Time = ? 5:45 a.m. Elapsed Time = 2 hours, 45 minutes 7:30 a.m. 6:30 a.m. 6:30 End Time = 8:30 a.m.

  11. Start Time = ? 3:13 p.m. Elapsed Time = 3 hours, 47 minutes 4:00 6:00 p.m. 5:00 p.m. 4:00 p.m. End Time = 7:00 p.m.

  12. Start Time = ? 2:46 p.m. Elapsed Time = 2 hours, 34 minutes 4:20 p.m. 3:20 p.m. 3:20 End Time = 5:20 p.m.

  13. Start Time = ? 7:19 p.m. Elapsed Time = 1 hour, 23 minutes 7:42 p.m. 7:42 End Time = 8:42 p.m.

  14. Start Time = ? 10:26 a.m. Elapsed Time = 1 hour, 23 minutes 10:49 10:49 a.m. End Time = 11:49 a.m.

  15. Start Time = ? 12:37 p.m. Elapsed Time = 2 hours, 36 minutes 2:13 p.m. 1:13 1:13 p.m. End Time = 3:13 p.m.
