There are 365 days in a year, well,unless is a leap-year, but we're assuming 365 days per year, now, "t" is how many years it takes for population to grow to "P" much, however, 1 day in year terms is really just 1/365 year or about 0.003 years, and 2 days is just 2/365 year, and 3 days is 3/365 year and so on, thus,

Answer:
5 minutes to run 1 kilometer
Step-by-step explanation:
Alonzo takes 12 minutes to run 6 times around a 400-meter track.
6 times around a 400 m track
400 * 6 = 2400 meters
It take 12 minutes to run 2400 meters
2400 meters = 2400/1000 = 2.4km
distance = 2.4 km and time = 12 minutes
Now we find our constant speed
2.4 = speed * 12
divide by 12 on both sides
speed = 0.2
so speed is 0.2 km per minute
Now we find out time when distance = 1km
Distance = speed * time
1 = 0.2 * t
divide by 0.2 on both sides
5 = t
So it take 5 minutes to run 1 kilometer
