On the weekend for every 2 minutes you spend watching puppy videos you spend 9 minutes watching regular tv. If you spend 572 min
harkovskaia [24]

Answer:

104 mins, 468 mins

Step-by-step explanation:

Let the time spent on puppy videos = 2x

Where x is the number of weekends.

Time spent on regular TV = 9x.

So total time spent is 572 mins

i.e 2x + 9x = 572

i.e 11x = 572

So x = 52.

So time spent on puppy videos = 2 X 52

                                                    = 104 mins

So time spent on puppy videos =  9 X 52

                                                      = 468 mins.
