The answer is 28 miles.
Displacement is not the same as distance. Total distance would be the sum of two distances: 40 + 12 = 52 miles.
However, displacement is the shortest distance from the initial and final position. Take a look at the attached image. Displacement is the difference of two distances:
D = 40 - 12 = 28 miles
The amount of medicine in the bloodstream decreases by 25% each hour.
<h3>Exponential equation</h3>
The standard exponential equation is expressed as:
y = ab^x
a is the initial amount
b is the rate
If b < 1, hence there is a declince
Given the expoenentia equation A(h)=600(0.75)^h,
b = 1 - r = 0.75
r = 1 - 0.75
r = 0.25
This shows that the amount of medicine in the bloodstream decreases by 25% each hour.
