The Attempt at a Solution

I can not figure out the following:

1. a. Calculate the depth to the ocean crust (sediment depth plus water depth). Now plot this depth versus longitude. The transect line was designed to cross over the mid-ocean ridge.
b. At what degree longitude is the mid-ocean ridge along this east-west transect? Locate the position of the mid-ocean ridge on this graph.
c. Now calculate the distance from the mid-ocean ridge to each of the sites. Give your answers in kilometers. Use the following information to convert degrees longitude to km.

Has anyone worked with this assignment before?

It doesn't look like you've made a very serious attempt at working on this problem. You wrote:

sediment depth plus water depth

"plus" means to add?
