B

130 m

C

30 m

D

100 m

Solution

The correct option is B

130 m 


We know that area under v-t graph gives displacement:-
So, Area = distance = s = area of triangle + area of rectangle

Area of triangle = (1/2) x base x height = (1/2) x 6 x 10 = 30 m

Area of a rectangle = length x breadth = (16 - 6) x 10 = 100 m

Total area = 130 m

Total distance = 130 m
