Distance is the total length the runner travels, regardless of the path taken. Displacement is the shortest distance between the starting and ending points, taking into account the direction traveled.
The runner travels around the rectangular track twice, which means they complete two laps. Each lap consists of the length (50 m) and the width (20 m) of the track. To calculate the total distance, we can use the formula:
Distance = 2 * (length + width)
Substituting the values, we get:
Distance = 2 * (50 m + 20 m)
Distance = 2 * 70 m
Distance = 140 m
So, the runner traveled a total distance of 140 meters.
Since the runner started and ended at the same point, the displacement is 0. The runner's net movement is zero because they returned to their starting point after two laps.
Displacement = 0 m
In summary, the runner traveled a total distance of 140 meters and had a displacement of 0 meters.
