Respuesta :

  • Paused for 30min

Starting time:-

  • 1:09PM=13:09+0:30=13:39

Now

Ending time:-

  • 3:47PM=15:47PM

Total active time:-

  • 15:47-13:39
  • 2:08hours

Or

Answer:

2 hours 8 minutes

Step-by-step explanation:

Let the total amount of time of Annabeth's being on the computer be x hours

since she paused using computer for a snack break for 30 minuted, our x turns out to be

[tex]x+0:30[/tex]

  • The initial time is 1:09 pm
  • The final time is 3:47 pm

Thus our equation would like

  • [tex]1:09+x+0:30=3:47[/tex]

solving the equation yields:

[tex]1:09+x+0:30=3:47\\\implies 1:39+x=3:47\\\implies x=3:47-1:39\implies \boxed{x=2:08}\rm hours [/tex]

hence,

Annabeth was on her computer for 2 hours 8 minutes

Note:

  • 1 Hour=60 minutes
