Answer 2

Explanation:

towns located in western hemisphere have time less than that in eastern hemisphere

1 There is difference of 4 minutes between each longitude.

time at town y 2 pm

time at town x 5 pm

longitude at town t 30 E

difference between time in town y and x=3 hours ( 180 minutes)

no. of longitudes between town x and y =180/4=45

location of town y= 75W

2 time at town x=7 30 pm

time at town y =4 pm

longitude in town x=60 W

time differnce =3 hours 30 min (210minutes)

no. of longitudes between town x and y = 210/4=52.5

location of town y=7.5 W
