Solution
Wednesday 9 p.m.
Explanation:
At 15° E, it's 10 a.m. Wednesday. The IDL is 165° west of 15° E, which is an 11-hour time difference (165° × 4 minutes = 660 minutes = 11 hours). Subtract 11 hours from 10 a.m., giving 11 p.m. Tuesday. Crossing the IDL westward changes the date back to Wednesday.
