The average speed is 97346 feet per hour approximately
<em><u>Solution:</u></em>
Given that blue whale calf swam from Miami, Florida, to Havana, Cuba, a distance of 228 miles, in 12 hours 22 minutes
To find: average rate of speed in feet per hour
<u><em>The speed is given by formula:</em></u>
![speed = \frac{distance}{time}](https://tex.z-dn.net/?f=speed%20%3D%20%5Cfrac%7Bdistance%7D%7Btime%7D)
From given information,
![distance = 228 \text{ miles }](https://tex.z-dn.net/?f=distance%20%3D%20228%20%5Ctext%7B%20miles%20%7D)
![time = 12 \text { hours } 22 \text{ minutes }](https://tex.z-dn.net/?f=time%20%3D%2012%20%5Ctext%20%7B%20hours%20%7D%2022%20%5Ctext%7B%20minutes%20%7D)
We know that,
![1 \text{ minute } = \frac{1}{60} \text{ hour}](https://tex.z-dn.net/?f=1%20%5Ctext%7B%20minute%20%7D%20%3D%20%5Cfrac%7B1%7D%7B60%7D%20%5Ctext%7B%20hour%7D)
Therefore,
![12 \text { hours } 22 \text{ minutes } = 12 + \frac{22}{60} \text{ hour } = 12.3667 \text{ hour }](https://tex.z-dn.net/?f=12%20%5Ctext%20%7B%20hours%20%7D%2022%20%5Ctext%7B%20minutes%20%7D%20%3D%2012%20%2B%20%5Cfrac%7B22%7D%7B60%7D%20%5Ctext%7B%20hour%20%7D%20%3D%2012.3667%20%5Ctext%7B%20hour%20%7D)
Substituting the values in above formula,
![\text { speed }=\frac{228}{12.3667}=18.4366](https://tex.z-dn.net/?f=%5Ctext%20%7B%20speed%20%7D%3D%5Cfrac%7B228%7D%7B12.3667%7D%3D18.4366)
Thus average speed is 18.4366 miles per hour
<em><u>Let us convert to feet per hour</u></em>
We know that,
1 mile = 5280 feet
Therefore,
18.4366 miles = 18.4366 x 5280 feet = 97345.248 feet
Thus average speed is 97346 feet per hour approximately
This would be 14137.17.
V=4/3 x π x r^3 = 4/3 x π x 15^3 ≈ 14137.16694
3/5 of 42000 is 25200 so the amount of people who did not vote is 16800 because the beginning amount of 42000 subtracted from 25200 gives you the final answer
If that's confusing the answer is 16800 votes didn't pick the winner
First the cost of $98 /yd³ by the conversion factor that
1 yd³ = 27 ft³.
($98 /yd³) (1 yd³ / 27 ft³) = $ 3 17/27/ft³
Let x be the width, the volume of the rectangular portion of the driveway is,
V = (8 ft) (1/3 ft) x = 8x/3 ft³
Using the given total cost of the protion,
C = $58.07 = (8x/3 ft³)(<span>$ 3 17/27/ft³)
x = 5.99957 ft
the answer is 6 feet. (rounded)</span>
