In this section, we learned to tell and write time to the nearest minute. We solved addition and subtraction problems about time.

the time Han got on the bus:

the time Han got off the bus:

Analog clock.

Here is one way to find out how much time Han spent on the bus:

  • Count up 3 minutes from 5:42 to 5:45, and then 15 minutes from 5:45 to 6:00.

  • Count up 30 minutes from 6:00 to 6:30, and then 7 more minutes to 6:37.

  • Add the minutes, , to get 55.
