Problema Solution
two rodents are seen within a period of ten minutes, it is believed that there is a breeding ground close by with approximately 600 rodents. if in one hour, joe saw twenty rodents pass by, what is the approximate rodent population near by?
Answer provided by our tutors
If 2 are seen in 10 minutes Joe can assume that in an hour 12 will be seen (which = 6 times 10 minutes) that is 12 rodents per hour.
So if 12 rats in 1 hour equals a nest of 600 what will 20 rats in 1 hour mean?
One way is 12 into 20 = 1.66666667
600 multiplied by 1.66666667 = 1000 rats.
Another way is to solve the ratio
12 : 600 = 20 : x
x = (600*20)/12
x = 1000 rats
the approximate rodent population near by is 1000 rats.
