Just take good care of your dog, feed good dry not supermarket junk, and make sure she is up to date on vaccinations - she should live a good, long life. Sounds as if you are doing all the right things already.
The average commercial jet liner travels about 550 mph, and the Earth is around 26,000 miles in circumference. If a commercial plane could make the trip without refueling, it would take over 47 hours. A large commercial jetliner has a range of about 5,000 miles, so it would need to land and refuel several times.
If we reverse that, we get that the speed is equal to the distance traveled over the time taken. We also know that the time it takes for the Earth to go once around the Sun is 1 year. So in order to know the speed we just have to figure out the distance traveled by the Earth when it goes once around the Sun.To do that we will assume that the orbit of the Earth is circular (which is not exactly right, it is more like an ellipse, but for our purpose it will do just fine).o in order to know the speed we just have to figure out the distance traveled by the Earth when it goes once around the Sun.
