19.) Impossible and spazz it doesn't matter the distance. If you want to average 60mph for a 1 mile trip you have to finish in 2 minutes. It takes 2 minutes to do 1 mile going 30mph therefore after the 2 minutes is up you cannot average 60mph.

20.) 4 inches presuming books are in order(am i missing something that was easy)

21.) Final math is done wrong. The problem is it started out 3x10, then jumped to 3x9+2. You can't just do 3x9, in an equation you always do Multiplication before addition/subtraction. This is prime example why.

22.) A lot of solutions, you can draw "outside the box" don't let the box limit to how long your lines are.

23.) Even, whenever a hand shake occours you add 2 since both people shook hands.

24.) 15 hand shakes. Assuming the quesiton only means each person only used 1 hand. Not specific
