Explanation:
Distance = (intial speed)X(Time) + 1/2(acceleration)X(Time) [Third equation of motion]
As initial speed is zero, therefore;
Distance = 1/2(acceleration)X(Time)
= 1/2 (6 X 15)
= 1/2 (90)
= 45 meters
Hence, the object traveled 45 meters.

[correct me if I'm not correct]
The average speed would be 0.65 m/s, therefore the correct option is (A).
The average speed is calculated by the formula
Average speed= (total distance/ total time)
The total distance of the trip=9.5+3.5+15=28 m
The total time of trip=43 sec
Therefore the average speed=28/43=0.65 m/s.
The answer to your question is true.
