Emergencies (an hence rescues) occur uniformly along a 4 mile stretch - ie: X is location and has a U[0,4] pdf.
d. What would be your answer if emergencies are twice as likely to arise in the northern two-mile stretch than in the southern two-mile stretch (but are uniformly distributed within each two-mile stretch)? Find the numerical solution to this part.The optimal location of the river rescue team when emergencies are twice as likely between 2 and 4 than between 0 and 2 (but uniformly distributed on each section).
