Kanye kunye nento sonke siqonda ukuba zininzi ikhilomitha kwikhilomitha elilodwa

Nangona umnqweno wehlabathi jikelele wehlabathi ukulungelelanisa, kuze kube yimhla kubekho iinkqubo zokulinganisa. Ngokomzekelo, kumazwe amaninzi, iililesi kunye neenyawo zisetyenziselwa ukulinganisa imida. Siye sijwayele inkqubo yeetrikri ukuba umgama, oboniswe ngeekhilomitha, ngamanye amaxesha uzisa umntu oqhelekileyo ukuba angene kwi-stupor. Eli nqaku lijoliswe ekuncedeni bonke abaneengxaki kwinkqubo yombuso. Ngoko, zingaphi iikhilomitha ezikhoyo kumamayela aseMelika?

Ukuze ungathwali umfundi ngembali yemvelaphi yale nqununu yokulinganisa, kunelungelo lokutsho ukuba livela kwiBukhosi baseRoma. Isetyenziswe ikakhulu kumazwe akhuluma isiNgesi nakwii-coloni zaseBrithani zangaphambili. Ngesinye isikhathi, ubukumkani baseRussia into encinane ayizange ishintshe ngokupheleleyo kwinkqubo enjalo.

Umbuzo olula othi "ngaphi kweekhilomitha ezili-1" kunzima ukuphendula. Kutheni? Ngenxa yokuba ixabiso liya kuhluka kumazwe nakwiindawo ezithile. Kunengqiqo ukucinga ukuba umfundi unomdla kwiimitha eziqhelekileyo, kodwa kukho ubunzima: kukho umhilomitha weemitha kunye nolwandle olwandle. Ukudibanisa akukhuthazwa, tk. Kuzo zonke ezili-10 "eziphosakeleyo" zeekhilomitha uza kufumana iikhilomitha ezingama-2 ezahlukeneyo - iphoso elingavumelekanga nakubalo lwemihla ngemihla.

Okokuqala, siya kuqonda ubuninzi beekhilomitha kwimitha ye-nautical - eyi-1852 yamitha. Akuzange kube njalo. Kodwa sinomdla kuphela kwintsingiselo yanamhlanje. Iimitha zamanxweme , ngokungaqhelekanga, zisetyenziselwa kwi-aircraft. Ezi iikhilomitha zikhethwe "i-NM", ngokwahlukileyo kumhlaba - "M".

Ngoku kuhleli ukufumana ukuba zininzi iikhilomitha enye kwikhilomitha elilodwa. Njengoko uqaphele, inkcazo ye "ngaphaya" ilahlekile, ngenxa yokuba Ukuba akukho ncazelo ichazwe, kucingwa ngokungagqibekanga ukuba umlinganiselo wenziwa kwiimitha eziqhelekileyo zaseBritish-American. Le mile ilingana neemitha ezili-1609 (kunye nephutha elincinane).

Xa ubala i-offhand, unokwandisa inani leekhilomitha nge-1.5 - kulula ukubala ngokuthetha, kodwa ukuchaneka koku kubalwa kuphantsi kakhulu. Oku kuza kulungeleka xa kungekho xesha lokubala okanye akukho kubakho ukubala. Ngokomzekelo, xa ufunda incwadi, xa ubude obunjalo abukhathaleli. Nangona kunjalo, ukubala okubaluleke kakhulu kukusebenzisa ixabiso elichanekileyo.

Kwaye ingxaki yokuguqulela ayikho enye. Uya kumangaliswa, kodwa ngelixa ucela "zingaphi iikhilomitha zihamba ngeekhilomitha enye," abantu abasebenzisa inkqubo ye-imperial bafumana uncedo olunganayo olufanayo kunye neemitha. Konke kuxhomekeke kukuphi uhlobo lomntu osetyenziswayo ukufaka isicelo. Ngethamsanqa, kuzo zonke izixhobo ezinzima kunye namaxwebhu, izikali ezimbini zinikezelwa ukulungelelaniswa kwabasebenzisi abavela kumazwe ahlukeneyo. Kwezinye iimeko, kuya kufuneka uthembele kuphela kwiimpawu zakho zeemathematika kunye nememori. Emva kwakho konke, ukuba ukwazi ukuba mangakanani amakhilomitha kwirele enye ayaneleyo, usadinga ukukhumbula ixabiso elichanekileyo xa ufuna. Ngako oko, akulimazi ukwenza into encinane ekuguquleleni ukusuka kwinkqubo enye ukuya kwenye.

Ubuncinane ngeveki, thabatha umgaqo wokuguqulela yonke iikhilomitha ukuya kumawaka, naphi na apho udibana nokukhankanywa kobude. Uza kubona, kwiintsuku ezimbalwa uza kuqala ukwenza ezo zibalo ngaphandle kokucinga.
