600
A 2
t(s).
B
2300
0 1
1) 1:1
3) 3:1
2) 2:1
4) 1:3
​

Answer 1

To find distance travelled, calculate area of v-t graph, which is equal of area of the spaces enclosed by the x and y axis. So distance = (4x2) + (2x2) + (2x2) =16m

For displacement, calculate area of spaces with positive velocity and subtract area enclosed with negative velocity.

Displacement= (8 + 4) - (2x2) = 8m
