Which context clue can best you determine the
meaning of the word latitude?
what type of context clue is this?
if you wanted to sail, it was impossible to keep a precise
record of time. and at sea, if you can't tell the time, you
don't how far east or west you are. it is relatively easy to
calculate latitude - your distance north or south of the
equator - by measuring the height of the sun above the
horizon at noon; but this won't let you calculate longitude
- your position east or west.
