That's more of a math question than astronomy. Calculate the orbit speed of the shuttle, and the circumference of the orbit. Compare that to the circumference of the Earth. Use the ratio to calculate the ground speed of the shuttle.
Orbit speed = 17,000 - 1000 = 16,000 mph
Orbit circumference = (3,963 + 75) miles x 2pi
Earth circumference = 3963 x 2pi miles
ratio = 0.98143
Ground speed = 0.98143 x 16,000 = 15,703 mph
Orbit speed = 17,000 - 1000 = 16,000 mph
Orbit circumference = (3,963 + 75) miles x 2pi
Earth circumference = 3963 x 2pi miles
ratio = 0.98143
Ground speed = 0.98143 x 16,000 = 15,703 mph
