How to approach elapsed time

Elapsed time measures how long an event lasts. Count forward from the start to a convenient hour, then continue to the ending time.

A timeline prevents errors when crossing an hour or noon. Add the separate jumps only after every interval is labeled.

Learning objectives

  • Find elapsed time
  • Determine missing start or end times
  • Use timelines across hour boundaries

Skills to review first

  • Telling time
  • Adding hours and minutes
  • Understanding 60 minutes in an hour
Worked example

Follow the reasoning step by step

How much time passes from 2:45 to 4:10?

  2. Count 1 hour from 3:00 to 4:00.
  3. Count 10 minutes from 4:00 to 4:10.
  4. Combine 15 + 60 + 10 = 85 minutes.
