Answer: Graph Y
Explanation:
The tool is floating at a rate of 2.0 meters every 1.0 seconds so both the distance and time are changing. Neither is constant which rules out graphs X and Z.
The distance is increasing as time increases which rules out Graph W which depicts a scenario where the tool is coming closer to the astronaut as time increases.
Correct option is therefore Graph Y as it shows the tool moving at a rate of 2.0 meters per second.
