Ahoy!

1) I have worked in that company SINCE last weekend.

2) We have played tennis FOR three hours.

3) Karen has watched tv SINCE the morning.

4) Malcon and Ashley have slept SINCE 8 pm.

5) They have studied for the exam FOR a week.

6) Mark has been out SINCE ten o'clock.

Eu receio que essas são as respostas, mas não tenho total certeza de tudo.

Explicação:

Since, que significa “desde”, "antigamente", indica na frase quando algo começou.

For é usado com o sentido de “há tanto tempo", "durante", "por" ou "para".
