Two ponies are at Extreme end of turntable with mass m
suppose turntable is moving with angular velocity 
Moment of inertia of Turntable and two ponies

Moment of inertia at that instant


conserving angular momentum as net Torque is zero



Thus we can say that angular velocity increases as they move towards each other.
