looking at the graph,
1) Displacement includes direction
Displacement from 8s to 16s = 15 - 6 = 9
Displacement fbetween 16s and 24s = 0 - 15 = - 15
Displacemet between 8s and 24s = 9 - 15
Displacemet between 8s and 24s = - 6m
2)
Distance does not include direction
from 8s to 16s,
distance travelled = 15 - 6 = 9 m
From 16s to 24s,
distance travelled = 15 - 0 = 15
Total distance between 8s and 24s = 9 + 15
Total distance between 8s and 24s = 24 m
