vaieri [72.5K]

If we know that 30% of the time is used after 9 minutes we can write this mathematically as:

$0.30x = 9$
By solving for x we can determine the total time allowed to play games and so:

$x = \frac{9}{0.30} = 30$
The total time allowed to play games is 30 minutes. Since 9 minutes have lapsed 30-9=21 minutes left to play.
