Why does a solar eclipse move from west to east?

Why do eclipse tracks move eastward even though the Earth rotates from west to east?

Answer:

Because the Moon moves to the east in its orbit at about 3,400 km/hour.  Earth rotates to the east at 1,670 km/hr at the equator, so the lunar shadow moves to the east at 3,400 – 1,670 = 1,730 km/hr near the equator. You cannot keep up with the shadow of the eclipse unless you traveled at Mach 1.5.
