Question 1200751
.
<pre>

(1)  In this problem, the word  "matches"  has the same meaning as the word "games".

     Thus 10 games is two times 5 games, and the rate remains the same.

     Hence, WHAT ?


     I do not write the answer, since it is OBVIOUS and lies on the surface.

     You should get it on your own.  It is as simple as to get that 2 x 2 is 4.




(2)  4 hours is four times 1 hour, and the rate remains the same.

     Hence, WHAT ?


     I do not write the answer, since it is OBVIOUS and lies on the surface.

     You should get it on your own.  It is as simple as to get that 2 x 4 is 8.
