To answer this question you must know that speed is only one magnitude, but velocity is a magnitude with an associated direction, that is, it is a vector.
For a circular movement like the one shown in the problem the velocity is defined as:
Where:
w = angular velocity
r = radius of the circumference
= angle of the object with respect to the origin
Speed is defined as:
.
In this problem we know that:
r = 30 m
So:
v = | V | = wr
v = (0.0503)(30)
v = 1.5079 m/s speed of the runner
On the other hand:
velocity of the runner
