Video Summary

The sixth Math Kangaroo Level 5–6 webinar focused on clocks, calendars, elapsed time, and related reasoning problems. Students began by finding that a clock’s minute hand moves 12 times faster than its hour hand.<br /><br />The session reviewed time units and 24-hour time, then worked through problems including:<br />- Rearranging the digits in 20:19 to find the next valid time using the same digits: 21:09.<br />- Comparing Earth and Mars weeks when a Martian day is 40 minutes longer: 4 hours 40 minutes longer per week.<br />- Counting strikes from an hourly clock over 24 hours, including its half-hour strikes: 180.<br />- Calculating a movie’s duration and a bicycle ride’s elapsed time.<br />- Finding a birth date one day less than a year apart, and estimating an age given in years, months, weeks, days, and hours.<br />- Calculating a pigeon’s distance from its travel time and speed.<br />- Finding the angle between clock hands after ten minutes: 35 degrees.<br />- Reasoning backward from a statement about the days of the week.<br /><br />The instructors encouraged students to show their work, use estimates and patterns, and guess rather than leave a contest question blank. They also recommended reviewing webinar recordings and trying past contests to track progress. A new webinar series is planned to begin in January.
