Answer:
The unit rate is equal to 
Step-by-step explanation:
we know that
The unit rate is the ratio of two measurements in which the second term is equal to one
In this problem to find the unit rate, divide the total cost of cereal by the total weight of cereal
so
therefore
The unit rate is equal to
Hello there! So, a fortnight is two weeks and two weeks is 14 days. You traveled 2,800 furlongs in two weeks. First off, let's divide the number of furlongs by the amount per mile. 2,800/8 is 350. That's 350 miles in two weeks. Now, we can divide 350 by 14 to find the amount traveled in 14 days. 350/14 is 25. There. You traveled 25 miles per day.
DB/dt = 1/5(100 - B)
5/(100 - B) dB = dt
-5 ln (100 - B) = t + C
Since B(0) = 20, then
-5 ln (100 - 20) = C
i.e. C = -5 ln 80
Thus -5 ln (100 - B) = t - 5 ln 80
or t = 5 ln 80 - 5 ln (100 - B) = 5 ln (80 / (100 - B))
When the weight = 40 grams
t = 5 In (80 / 100 - 40) = 5 In (80 / 60) = 5 ln (4/3) = 1.438 days
Rate of weight gain = 40 / 1.438 = 27.8 grams per day
When the weight = 70 grams
t = 5 ln (80 / 100 - 70) = 5 ln (80 / 30) = 5 ln (8/3) = 4.9 days
Rate of weight gain = 70/4.9 = 14.27 grams per day.
Therefore, the duck gains weight faster when it weighs 40 grams.
