Answer:
Until the late 19th century most people used local solar time so that noon was when the sun was directly overhead, and each town had its own definition. Transport was slow, so it did not matter that the time in a town miles away varied by a few minutes. The advent of railways necessitated more accurate time keeping and time zones were introduced to keep an entire region on the same time1. Time zones follow political boundaries so that local time may be up to 2 hours different from solar time.
Local Solar Time (LST) and Local Time (LT)
Twelve noon local solar time (LST) is defined as when the sun is highest in the sky. Local time (LT) usually varies from LST because of the eccentricity of the Earth's orbit, and because of human adjustments such as time zones and daylight saving.

Explanation:
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).
(i).1°N- 4 minutes
15°E - 4 minutes x 15 = 60 minutes
(ii). 1°N - 4 minutes
75°W = 4 minutes x 75 = 300 minutes
Approx. 6 hours
