Last Saturday, Jay spent 6 h playing games, studying, and talking to his friends. He spent 2/5 of the time playing games and 1/2 of the time studying. How many minutes did he spend talking to his friends?
2 / 5 • 6h = 12 / 5 h = 2.4h
1 / 2 • 6h = 3h
He spent on playing games and studying:
2.4h + 3h = 5.4h
He spend 6h - 5.4 h = 0.6h talking to his friends.
1h = 60 min
0.6h = 0.6 • 60 min = 36 min
