Answer
4.6 m/s to the right.
Explanation
Velocity is a vector quantity. It has both magnitude and direction.
Taking the 5.8 m/s moving to the right as positive, then the 1.2 m/s moving to the left will be negative.
∴ 5.8 + -1.2 = 5.8 - 1.2
= 4.6 m/s.
The resultant velocity vector is 4.6 m/s to the right.
