Answer:
The students velocity is 3 ft/s
Explanation:
Velocity (ft/s)
Velocity is the Total distance covered over time taken to cover the distance. D/t
Overall movement to the right is the distance covered.
Total distance covered = 30 ft - 10 ft + 20 ft
= 40 ft
Time taken = 20 s
Students velocity = 40 ft / 20 s
Students velocity = 2 ft/s
The student's displacement (straight-line distance between initial and final positions) is 40-ft right.
Velocity = displacement / time
Velocity = 40-ft right / 20 sec
Velocity = 2 ft/sec right .
