Later, when seamen began t use the cmpass in the 12th century they culd calculate lngitude using cmplicated mathematical tables．
后来，当12世纪海员们开始使用指南针的时候，他们就可以用复杂的数学表来计算出经度了。
using cmplicated mathematical tables 是现在分词短语作状语，表示手段。
The cmpass has a special magnetic pinter which always indicates the Nrth Ple, s it is used t help find the directin that the ship needs t g. pinter 是先行词, which 是引导词, 在从句中作主语, 引导后面定语从句always indicates the Nrth Ple; s 后面引导的是结果状语从句; the directin 作为先行词, that是引导词, 引导定语从句the ship needs t g。
指南针有一个特殊的磁针，始终指着北极。因此人们用它来帮助找出船只所要去的方向。

Speed and time are imprtant in findingut the lngitude f a ship because the earth mves fifteen degrees westwards every hur. If yu knw yur directin, speed and time, yu can wrk ut the apprximate lngitude r change in yur psitin in relatin t the stars.
Why are speed and time imprtant in wrking ut the lngitude f a ship?
The psitin f the sun and stars are useful fr wrking ut latitude because they are fixed pints in the sky and their mvements in relatin t the earth are already knwn. S they can be used t measure a ship's psitin.
3 Why is the psitin f the sun and varius stars useful fr wrking ut latitude?
The sailrs wuld need t be excellent navigatrs, able t cpe with bth ht and cld weather, experienced in sailing thrugh very bad weather and able t c-perate in a team.
