Madyson Mckee · Answer 1

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

Jonathan Cantrell · Answer 2

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.
