You can put this solution on YOUR website!
The 600 passengers for 3 weeks quantity of food can be put into how many weeks for 1 passenger, and you then will know the rate per passenger; just assume you have some known quantity of food. You can simply call this some variable, p, the quantity of food as the "sufficient food".

If 600 passengers consume p in 3 weeks, then
1 passenger consumes p in 3*600=1800 weeks.
p%2F1800 is the one-passenger consumtion rate

Question, how much time t for 800 passengers to consume p?
%28p%2F1800%29%2A800%2At=p
%28800%2F1800%29t=1
t=18%2F8
t=9%2F4
highlight%28t=2%261%2F2%29 weeks.
