Elia rode her bicycle from her house to the beach at a constant speed of 181818 kilometers per hour, and then rode from the beach to the park at a constant speed of 151515 kilometers per hour. The total duration of the rides was 111 hour and the distances she rode in each direction are equal. Let bbb be the number of hours it took Elia to ride from her house to the beach, and ppp the number of hours it took her to ride from the beach to the park.

the answer   is 200

step-by-step explanation:

this is a problem about poisson probabilities.   i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.  

here's how you can see a poisson distribution coming.   when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution.   this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot.   there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything.   the form of the distribution is

  probability of n chips = {[e^(-x)]*(x^n)} / (n! )
