Geology please help?

The oldest rocks in the South Atlantic Ocean, immediately adjacent to the African and South American continental shelves, are 120,000,000 years old.

Part 1.b. Calculate the average rate of seafloor spreading for the South Atlantic Ocean over its entire existence.


33.3 km/Myr = 33.3 mm/yr


0.03 km/Myr = 3 mm/yr


0.03 km/Myr = 0.03 mm/yr


33.3 km/Myr = 3,330 mm/yr

    I bet you have that information in your textbook or maybe in Part 1.a of your homework.
