Suppose a boat needs to travel in water with a depth of at least 3 meters. Given the two-dimensional ocean depth map shown below, which of the following would be the safest path for the boat to travel, west-to-east, across this ocean? straight across at 30.4° N latitude straight across at 30.3° N latitude straight across at 29.5° N latitude diagonally from the top left corner (30.4° N, 90.4° W) to the lower right corner (29.5° N, 89.5° W)
