Calculations Involving Time
Akopọ
Time is the one quantity that refuses to work in tens. Sixty seconds in a minute, sixty minutes in an hour, twenty-four hours in a day: this base of sixty trips up anyone who treats a clock like a decimal number. Getting time arithmetic right is essential for timetables, schedules and any problem set in the real world.
In this lesson you will calculate with units of time, convert between the 12-hour and 24-hour clock, and read timetables to work out durations and arrival times. The key idea throughout is that time is counted in sixties, not tens, so a decimal answer must be read with care.
Awọn Afojusun
- Calculate with units of time and read clocks and timetables, including the 12-hour and 24-hour clock.
