What is the average speed of the object over the whole time interval?

Question

An object moves to the right 10.0m from the starting point in a time of 1.0s, then moves 13.0m to the left in the time of 2.0s and finally to the right in a time of 1.0s. What is the average speed of the object over the whole time interval?

Please show work thanks!

Answer 1

Please

Average speed = total distance / total time. It's not possible to find this because we need to know the distance moved to the right during the last 1.0s which is missing.
