Measurement & data

What you’ll practice

Find a duration between two clock times.

Count the minutes from the start time to the finish time. Watch for a “next day” label when the interval crosses midnight.

How this skill works

Convert HH:MM to 60 × hours + minutes.

Subtract the start from the finish. If the finish is labeled next day, add 1,440 minutes to it first.

Worked example

A task starts at 09:45 and finishes at 11:10. How many minutes pass?
  1. 09:45 is 9 × 60 + 45 = 585 minutes from midnight.
  2. 11:10 is 11 × 60 + 10 = 670 minutes.
  3. 670 − 585 = 85 minutes.

Answer: 85 minutes

Teaching notes

  • Crossing an hour does not mean adding 100 minutes.
