Answer:
793.25 mi/hr
Step-by-step explanation:
Given that:
The radius of the earth is = 3030 miles
The angular velocity = ![\dfrac{\pi}{12} rads](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cpi%7D%7B12%7D%20rads)
If a jet flies due west with the same angular velocity relative to the ground at the equinox;
We are to determine the How fast in miles per hour would the jet have to travel west at the 40th parallel for this to happen.
NOW;
Distance s is expressed by the relation
s = rθ
![s = 3030(\frac{\pi}{12} )](https://tex.z-dn.net/?f=s%20%3D%203030%28%5Cfrac%7B%5Cpi%7D%7B12%7D%20%29)
s = 793.25
The speed which depicts how fast in miles per hour the jet would have traveled is :
![speed (v) = \frac{s}{t}](https://tex.z-dn.net/?f=speed%20%28v%29%20%3D%20%5Cfrac%7Bs%7D%7Bt%7D)
![v = \frac{793.25}{1}](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7B793.25%7D%7B1%7D)
v = 793.25 mi/hr
Hence, the jet would have traveled 793.25 mi/hr due west at the 40th parallel for this to happen.
