Answer:

Let the total distance = 3x,

The travel takes place in 3 parts:

x distance at 2ms

−1

x distance at 3ms

−1

x distance at 6ms

−1

The time taken in each individual travel is:

t

1

=

2

x

t

Hence the total time taken is :

t

=x

Total distance travelled = 3x

Average velocity =

3x

=3ms

−1

Hence option A is correct.
