The two skaters will move with a common speed of 1.19 m/s.
Explanation:
Given that,
Mass of Alex, 
Initial velocity of Alex, 
Mass of Barbara, 
Initial velocity of Barbara, 
After the collision, the two skaters move together at a common velocity. Let V is the common velocity. Using the conservation of momentum as :
Magnitude of final velocity:
So, the two skaters will move with a common speed of 1.19 m/s.
