Question 318556: A jet is traveling westward with the sun directly overhead. That is, the jet is on a line between the sun and the center of the earth. How fast must the jet fly in order to keep the sun directly overhead? Assume that the earth’s radius is 3960 miles, the altitude of the jet is low, and the earth rotates about its axis once in 24 hours.

The Earth has a circumference of 2π(3960)= 24881.41382 rounded to 24881
That means it rotates 24881/24 = 1036.708333
The jet will have to fly about 1037 mph.
