At 18h32 local time, the navigator of the ship received a Moscow time signal transmitted at 11h. Determine the longitude of the ship if the longitude of Moscow is known (2h30 m).
2 hours = 30 °; 60 time minutes corresponds to 15 °, therefore 30 time minutes corresponds to 7.5 °. Accordingly, the longitude of Moscow is 37.5 ° E.
The time difference between the ship and Moscow is 7 hours 32 minutes.
60 time minutes corresponds to 15 °; therefore 7 o’clock corresponds to 105 ° longitude; 30 time minutes corresponds to 7.5 °; 4 time minutes corresponds to 1 °; 2 time minutes corresponds to 0.5 °. Thus, 7h 32m corresponds to 113 °.
The ship is located 113 ° east of Moscow.
Hence, the longitude of the ship is 113 + 37.5 = 150.5 ° E.
