The distance traveled by the pendulum from X to Y is
the length of the arc if X and Y are joined.

Given data: r=120 and θ=30

The length of an arc is $$(\frac{θ}{360}) × 2π × r$$
Therefore, the distance traveled is $$\frac{1}{12} * 2π × 120 = 20π$$(Option D)

$$\frac{30}{360}=\frac{1}{12}=$$ the fraction of a circle the pendulum arc is.

If this were a circle, circumference would =
$$2\pi r = 240\pi$$

$$\frac{1}{12} *240\pi = 20\pi =$$ distance traveled by the pendulum.
