Answer:

$\huge\underline\mathcal\red{Answer}$

• Find a convenient time zone at 40° W. From the map, time zones include UTC-4 and UTC-5. So your 10:00 correspond to 14:00 or 15:00 UTC.
• Find a convenient time zone at 40° E. From the map, time zones include UTC+2, UTC+3 and UTC+4. So the time there could be 17:00, 18:00, 19:00 or 20:00. One time that it most certainly would not be is 15:20.
