360° covers in 24 hours
then 1° in = 4 minute
1.) 20°W = 20x4= 80 minutes = 1hr : 20 mins
Time at place one = 12 - 1: 20 = 10 :40 Am
2.) 30° E = 30x4= 120minutes= 2hr : 00mins
Time at place two= 12 + 2:00 = 14:00 hours or 2:00 pm
3) 15°W = 15 x 4 = 60 minutes = 1hr: 00mins
Time at place three = 12: 00 - 1: 00 = 11:00 AM
