The speed is 40 cm/sec or 0.4 m/sec

Explanation:

This is a distance speed time question.

#360 # cm is a distance, and #9 # seconds is the time taken

"How fast ?" is asking for the speed.

#"speed" = "distance"/"time"#

#"speed" = 360/9 = 40 " cm per sec"#

A more usual unit for speed would be m/sec, which would be
#0.4# m/sec
