Problem
A rotating circular platform has a radius of 0.40m. One insect sits at the rim (point A), while another sits 0.25m from the centre (point B). The platform turns through 7.5 revolutions.
(i) Calculate the linear distance travelled by point A.
(ii) Calculate the linear distance travelled by point B.
(iii) How much farther does point A travel than point B?
