Physics momentum question?

A 58 kg ice skater traveling at 3.2 m/s to the north suddenly grabs the hand of a 61 kg skater traveling at 10.1 m/s in the opposite direction as they pass. The two skaters continue skating together with joined hands. What is the final velocity of the two skaters?

no idea how to do this..

    initial momentum = final momentum

    m1vi + m2v2 = (m1+m2)v2

    v2 = (m1vi + m2v2)/(m1+m2)

    v2 = [58(3.2) - 61(10.1)] / [58+61]
