Question

A runner is running along a rectangular track with length of 50m and width 20m he travels around the track twice finally running back to starting point if the total time he tales to run around the track is 100sec determine average speed and average velocity

Answer 1

Answer:

Average speed = 20 m/s

Average velocity = 0 m/s

Explanation:

50 x 20 = 1000m

Runner travels around the track twice so:

1000 x 2 = 2000

Time taken = 100 sec

Average speed = 2000/100 = 20 m/s

Average velocity = displacement/time

displacement = 0

Average velocity = 0/100 = 0m/s
