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
 
...to east in one hour? Space shuttle would orbit the earth, if given an initial horizontal speed of 17,000 mph at around 75 miles above earth surface where atmosphere is out and air resistence is no more. The earth's self rotation speed is 1,000 miles per hour.

Given this shuttle traveling from west to east, what would be the ground distance this shuttle traveled in one hour?

Notice that earth and our shuttle go in the same direction.
