Sagot :

Watched TV 1,800s friday

1.5h saturday

45 minutes sunday

How many minutes?

First we need to convert seconds and hours to minutes:

[tex]\begin{gathered} 1\text{ hour - 60 minutes} \\ 1.5h\text{ - x } \\ x=\text{ }\frac{\lparen60min\rparen\lparen1.5h\rparen}{1h} \\ x=\text{ 90 min} \\ \\ 60\text{ seconds - 1 minute} \\ 1,800\text{ seconds - x} \\ x=\frac{\lparen1,800s\rparen\lparen1min\rparen}{60\text{ s}} \\ x=\text{ 30 min} \end{gathered}[/tex]

So now we have to add all the minutes watched:

[tex]\begin{gathered} Total\text{ watched= 90 min + 30 min + 45 min} \\ Total\text{ watched= 165 minutes } \end{gathered}[/tex]

Mike watched a total of 165 minutes on TV.
