Displacement A-B
The area under a v-t graph gives the object’s displacement during that time period.AreaA-B = ½ base x height
= ½ (1 s x 10 m•s-1)= 5 m= 5 m upward

Displacement B-C
The area under a v-t graph gives the object’s displacement during that time period.AreaB-C = ½ base x height
= ½ (2-1)s x (-10-0) m•s-1
= ½ (1s x -10 m•s-1)= -5 m= 5 m downward

Displacement A-C
The combined areas under the A-B and B-C lines for the v-t graph gives the displacement for interval A-C.AreaA-C = AreaA-B + AreaB-C
= 5 m – 5 m= 0 m
