With constant speed it will take her : 405 ml / 45= 9 hours of drive
any of the 34 cars can finish first
any of the remaining 33 cars can finish second
any of the remaining 32 cars can finish third
Thus, the top 3 finishes can be done in (34)(33)(32) = 35904 ways
if she has 9, add 7. you have 16. divide it by half, 8. subtract 3 and you get 5.
