7. 50 matches to 50 winners, round 2 would have 25 matches to25 winners, round 3 would have 12 matches to 12 winners
round 4 has 6 matches to 6 winners, round 5 would have 3 matches to 3 winners, round 6 would have 2 matches to get 2 winners, these 2 would play for the championship so.......... 50 + 25 + 12 + 6 + 3 + 2 + 1 =99
but i was readin it and i think there is 2 answers... the 2nd answer i got was 111 matches.. its complicated.. but yeah.. dunno if its right...

8. 55+80=135mph. Divide speed by 60 minutes, traveling each minute=2.25 miles/minute. soo... 2 minutes before impact they are 4.5 miles apart...

9. 60/30 = 2 hours, and the trip back = 60/20 = 3 hours. so... the 120 mile trip = 120/5 = 24 mph.

10. 100 pieces are made in 99 cuts. The last cut made in 2 pieces instead of only one piece. so... 297 sec
