Velocity relative to the surface of ice

A 45.0 kg girl is standing on a 170 kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat, frictionless surface. The girl begins to walk along the plank at a constant velocity of 1.53 m/s relative to the plank.

a) What is her velocity relative to the surface of ice?

b) What is the velocity of the plank relative to the surface of ice?
