Resposta:

1. 10 de outubro de 2005 às 11 horas;

2. 10 de outubro de 2005 às 18 horas;

3. 10 de outubro de 2005 às 9 horas;

Explicação: os fusos horários são determinados por meio de uma divisão do mundo em 24 fusos horários distintos. Essa divisão se deve à rotação da Terra: em 24 horas, a Terra gira em torno de seu próprio centro, portanto, em 1 hora, ela se move 15 °.

O fuso horário inicial é o horário de Greenwich e passa pela Grã-Bretanha.

Dele, a cada 15 °, passa-se 1 hora a mais, se a posição do ponto estiver a leste de Greenwich, e 1 hora a menos, se estiver a oeste de Greenwich.

espero que tenha ajudado! :)

Answer: 1. October 10th, 2005 at 11 o'clock;

2. October 10th, 2005 at 18 o'clock;

3. October 10th, 2005 at 9 o'clock;

Step-by-step explanation: Time zones are determined through a division of the world in 24 distinctive timezones. This division is due to the rotation of the Earth: in 24 hours, the Earth spins around its own center, so in 1 hour, it moves 15°.

The initial timezone is Greenwich Mean Time and passes over Great Britain.

From it, at each 15°, it is 1 hour more, if the point's position is at the east of Greenwich and 1 hour less, if it is at the west of Greenwich.

For example, in each situation from the question:

1. A point is located at 45° due west:

45/15 = 3,

There are a difference of 3 time zones and it is due west:

The date and time is October 10th, 2005 at 11 o'clock.

2. A point is 60° due east:

60/15 = 4

There are a difference of 4 time zones and as it is east:

The date and time will be October 10th, 2005 at 18 o'clock.

3. Point at 75° west:

75/15 = 5

There are a difference of 5 time zones, west:

The date and time will be October 10th, 2005 at 9 o'clock.
