find common denominators, 8/11 - 4/15 = 120/165 - 44/165 = 76/165. That is your answer is simplest form.
It is: 165/15 = 11
15 / (3/11) = 15* (11/3) = 5*11 = 55

The time difference between two longitudes can be calculated by dividing the distance between the longitudes by 15 degrees, as the Earth rotates 15 degrees per hour. Each 1 hour represents a time difference of 1 hour (60 minutes) between the two longitudes.
