From January $26,1977,$ to September $18,1983,$ George Meegan of Great Britain walked from Ushuaia, at the southern tip of South America, to Prudhoe Bay in Alaska, covering $30600 \mathrm{~km}$. In meters per second, what was the magnitude of his average velocity during that time period?

Key Concepts

Average Velocity

Average velocity is defined as the total displacement divided by the total time taken. It is a vector quantity that describes how quickly an object changes its position, giving both magnitude and direction. In calculations where only the magnitude is needed, the focus is on the absolute value of displacement over time.

Unit Conversion

Unit conversion is the process of converting a measurement from one unit to another. In physics problems, this often involves converting distances such as kilometers to meters, or time intervals, usually from days, months, or years to seconds, to ensure consistency in units across all quantities used in formulas.

Time Interval Calculation

Time interval calculation involves determining the difference between two given dates or times and then converting that difference into a desired unit of time, typically seconds, for use in physics problems. Accurate time calculation is crucial in computing rates such as velocity, where the total elapsed time must be correctly determined.
