How do longitudes help us to calculate time?​

Answer»

Each degree is divided into minutes and minutes into seconds. The Earth takes 24 HOURS to complete one rotation or to cover 360° of LONGITUDES. This MEANS that the Earth covers 15° of longitudes every hour. One degree of longitude takes 4 minutes (1 hour = 60 minutes, divided by 15° per hour = 4 minutes per longitude).
