Answer:
68.57 mile/hour
Explanation:
The distance from Yakima to Ellensburg is 50 miles and you travel with 60 miles/hour for the first 25 miles, then 80 miles/hour for the last 25 miles. The easy way to solve this question is to find the total time needed to travel.
The time needed to travel 25 miles with 60 miles/hour speed will be: 25 miles/ (60 miles/hr)= 0.42 hr
The time needed to travel 25 miles with 80 miles/hour speed will be: 25 miles/ (80 miles/hr)= 0.31 hr
Total time needed to travel 50 miles will be: 0.41 hr + 0.31hr = 0.73 hr
The average speed will be:
average speed= sum of travel distance/ sum of time needed= 50 miles/ 0.73hr= 68.57 mile/hr

Explanation:
The frequency of sound waves received by the microphone influences the output or pitch of the sound obtained from the microphone.
The higher the frequency of the sound received by the microphone, the higher the output of the microphone and vice versa. This is because, the higher the frequency of sound, the higher the oscillations produced and the greater the output of the microphone.
The rise and fall in the pitch of sound waves as the frequency of sound waves varies is called inflection.

Explanation:
It's a good thing to claim this was speed and not velocity.
Givens
d = 40 meters
t = 5 seconds
V = ??
Formula
v = d/t
Solution
v = 40 m/5 sec
v = 8 m/s
If you really wanted to get picky, you should convert the distance to yards which is how distance is measured in football
1.09 yards = 1 meter
d = 40 * 1.09 = 43.74 yards.
t = 5 seconds
v = 43.74/5 = 8.749 yards / second.
