From 4 p. m. to 5: 30 p. m., carolos, lisa and toni took turns playing the same computer game. carolos played for 1/2 hour, and lisa played for 3/4 hour. for how many minutes did toni play the game?

Hi!

From 4 p.m to 5:30 p.m. there is hour and a half, or 90 minutes.

Carolos played for 1/2 hour = 30 minutes.

Lisa played for 3/4 hour = 45 minutes.

Toni played = 90 - 45 - 30 = 15 minutes.

Hope this helps!
