This problem offers students an
opportunity to test their understanding of division and to consider
different ways in which calculators can be used.

The interactivity also offers students a chance to explore the
relationships between the angles of turn that produce the same
vertical and horizontal displacements.

Follow up questions could include:

Through what angle(s) between $0$ and $360$ degrees would the dot have had to turn if it was to finish the same distance above/below the horizontal axis?

If I type $20$ $000$ $\div$ $360$ into my calculator the answer on the screen is $55.555556$

How can this help me answer the question?

Similarly for $40$ $000$ degrees.

If I type $40$ $000$ $\div$ $360$ into my calculator the answer on the screen is $111.11111$.

Similarly for $80$ $000$ degrees.

If I type $80$ $000$ $\div$ $360$ into my calculator the answer on the screen is $222.22222$.

Similarly for $250$ $000$ degrees.

If I type $250$ $000$ $\div$ $360$ into my calculator the answer on the screen is $694.44444$.

And what about horizontal displacements to the left/right of the vertical axis?

Students could make up their own questions...
