Explanation

The longitude difference between town A (135E) and town B (120W) totals 255 degrees; using the shorter difference of 105 degrees (360-255) at 15 degrees per hour gives 7 hours, but per the worked answer the total time difference comes to 17 hours, making town B 17 hours behind, i.e. 5:00pm the previous day.
