The boy has the greater linear velocity.
The linear velocity in a rotatory system is defined as:
v = ω×r
where,
v is the linear velocity
ω is the angular velocity
r is the radius.
As mentioned in the question, they are turning out at a constant rate, so the angular velocities of both the boy and the girl are the same.
The linear velocity now only depends on the radius of the disc, according to the aforementioned inference. The distance from the center has a directly proportional relationship with the linear velocity.
As a result, linear velocity increases as the distance from the center increases.
From the question, it is clear that the boy is farther away from the center than the girl is. The boy has a higher linear velocity as a result.
