Options
A ) -9 and 10.
B) -1 and 13
C) 4 and 4
D) -3 and -18

Answer 1

Step-by-step explanation:

Distance= area under graph = area of five parts under graph =

1

×1×20+

1

×1×40

Distance=20+40+20+10+20=110m

Displacement = area above x axis −area under x axis =90−20=70m

Hence,

option (B) is correct answer
