her average speed is 180 meter/60seconds
which is 3m/s
her average velocity is zero,since displacement is zero

Answer:
avg speed : 3m/s and avg velocity: 0m/s
Step-by-step explanation:
It will be simple if you understand the basic definition stuff i.e.
Average speed: Total distance travelled means entire path/total time in preferable units
Average velocity: Total displacement (shortest distance between initial and final point) / total time
