Answer:
Waylon ran at a speed of 9 miles per hour.
Explanation:
A hour equals to 60 minutes, then, the equivalent time is found:
![t = 25\,min \times \left(\frac{1}{60}\,\frac{h}{min} \right)](https://tex.z-dn.net/?f=t%20%3D%2025%5C%2Cmin%20%5Ctimes%20%5Cleft%28%5Cfrac%7B1%7D%7B60%7D%5C%2C%5Cfrac%7Bh%7D%7Bmin%7D%20%20%5Cright%29)
![t = \frac{5}{12}\,h](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B5%7D%7B12%7D%5C%2Ch)
Let suppose that Waylon runs at constant speed, so that equation is equal to:
![v = \frac{s}{t}](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7Bs%7D%7Bt%7D)
Where:
- Speed, measured in miles per hour.
- Travelled distance, measured in miles.
- Time, measured in hours.
If we know that
and
, then:
![v = \frac{\frac{15}{4}\,mi }{\frac{5}{12}\,h }](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7B%5Cfrac%7B15%7D%7B4%7D%5C%2Cmi%20%7D%7B%5Cfrac%7B5%7D%7B12%7D%5C%2Ch%20%7D)
![v = 9\,\frac{mi}{h}](https://tex.z-dn.net/?f=v%20%3D%209%5C%2C%5Cfrac%7Bmi%7D%7Bh%7D)
Waylon ran at a speed of 9 miles per hour.
