A snail crawls 5/8 inches in 3/4 minute. What is the snail's speed in inches per minute? Write your fraction in simplest form.

5/12 inches per minute

Step-by-step explanation:

If A snail crawls 5/8 inches in 3/4 minute, then;

5/8 inches = 3/4 minute

we are to fine the distance covered in a minute;

x inches = 1 minute

Divide both expressions

5/8x = 3/4

24x = 20

12x = 5

x = 5/12

Hence the snail covered 5/12 inches per minute

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! )
