I believe the correct answer from the choices listed above is option B. Absolute threshold refers to the lowest intensity at which a person can detect stimuli. It <span>is the smallest level of energy required by an external stimulus to be detectable by the human senses. Hope this answers the question.</span>
<h2>Calculating the Speed given the Distance and Time</h2><h3>
Answer:</h3>
![4.\overline{4} \frac{\mathrm{km}}{\mathrm{min}}\\](https://tex.z-dn.net/?f=4.%5Coverline%7B4%7D%20%5Cfrac%7B%5Cmathrm%7Bkm%7D%7D%7B%5Cmathrm%7Bmin%7D%7D%5C%5C)
<h3>
Explanation:</h3>
The speed,
, is calculated by
where
is the distance traveled and
is the time. We are given the distance traveled of the bus,
, and the time it has traveled,
. So, the speed of the bus,
, is calculated as...
![r =\frac{200 \mathrm{km}}{50 \mathrm{min}} \\ r = \frac{40 \mathrm{km}}{9 \mathrm{min}}](https://tex.z-dn.net/?f=r%20%3D%5Cfrac%7B200%20%5Cmathrm%7Bkm%7D%7D%7B50%20%5Cmathrm%7Bmin%7D%7D%20%5C%5C%20r%20%3D%20%5Cfrac%7B40%20%5Cmathrm%7Bkm%7D%7D%7B9%20%5Cmathrm%7Bmin%7D%7D)
The speed of the bus is
or
.
Dont know but i think is 567
