Task goals

  • Convert between units of time (seconds, minutes, hours, days), including converting decimal hours to hours and minutes.
  • Convert a time between 12-hour (am/pm) and 24-hour notation.
  • Find a duration (elapsed time) between a start and end time, or find a finish time given a start time and a duration.
  • Solve speed, distance, and time problems using the relationship speed = distance divided by time, including converting the answer's units.
  • Solve real-world duration and rate problems that combine several steps, such as time-zone differences or splitting a job's time evenly.
  • Identify and correct an incorrect claim about converting between decimal hours and hours-and-minutes, such as that 2.5 hours equals 2 hours 50 minutes.
