hour to play video games
Convert to minutes


2) It takes him
hour to set up the system
Convert to minutes

3) Find time available to play video games

4) Each round of his favorite game takes
hour
Convert to minutes

5) Divide the time available to play video games by the time each round of his favorite game

therefore

therefore
<u>the answer is</u>
