Answer 2

12 pull

As 48 seconds + 20 seconds push = 68 seconds

Explanation:

Because she did 10 push = 20 seconds = 2 seconds each

12 pull = 48 seconds = 4 seconds each

= 68 seconds combined.

Workings;

18 seconds found for the first set

We then find a divider of 68 and know that

6 x 3 = 18 seconds push

12 x 3 =36 seconds pull T= 54

14 left over = 1 x 12 seconds pull

+ 2 seconds push

= 10 push = 20 seconds combined.

= 12 pull = 48 seconds combined.
