Compute the solution of the following problem

Problem- According to the Nuvel-1A plate model the Euler pole describing the motion of the South American plate relative to the African plate is located in the vicinity of Southern Greenland (i.e., 62.5°N, 39.4°W). The angular velocity of South America relative to Africa about that pole is 0.31°/Myr (clockwise). Given this,

Part 1- What is the half-spreading rate along the Mid- Atlantic Ridge near

i- Ascension Island (8.0°S, 14.3°W) in units of cm/yr?

ii- Saint Helena (16.0°S, 5.6°W) in units of cm/yr?

iii- Tristan da Cunha (37.0°S, 12.3 °W) in units of cm/yr?

Part 2- Describe any variation you find in the spreading rate from location to location. At what latitude would you expect to find the fastest spreading occurring along the MAR? Why?

Clue: For simplicity, assume the MAR near each of the islands lies on the same meridian as the Euler pole (i.e., longitude is 39.4°W). This will introduce a small error into your results, but it will not change the overall picture.

I need assistance to find the half-spreading rate.
