I had a big mistake in the comment above, it's 220 km/h or about 60 m/s.
cos(28)=0.88
0.12*(2*pi*7000 km) = 5300 km
5300 km / 24 h = 220 km/h
220 km/h / 3.6 m/s/km/h = 61 m/s
For example Cape Kennedy is 28 degrees north. If you fly to the equator, you get another 200 m/s.
Depends a bit to which orbit you're launching though.
Another good thing is flexibility if you are more constrained by launch windows in a stationary launch location. Hard to explain.
