Convert this speed to miles per hour. (There are about 1.6km in 1 mile and 3600 s in 1 h)

What's the problem? You have the conversion factors. 8km = 8/1.6 miles, 1 sec = 1/3600 hr. First you have 8/1.6 mi/sec = 8/1.6 mi/sec*3600 sec/hr = [ ]mi/hr (you figure it)

A low earth orbit requires a velocity of about 5.5 miles per second. A rocket launched from the equator already has a bit more than 1,000 miles per hour (a bit less than 1/3 mile per second) so it is easier, in terms of change of velocity to launch from the equator than to launch from more northern or southern latitudes. Satellites in polar orbits take much more increase in velocity, because the rotation of the earth does not add to the required velocity for a stable orbit. To get the velocity, if your numbers are correct, divide 8 km/sec by 1.6 to get MPH.

Come on this is simple. Divide 8 by 1.6 then mulitply is by 3600 and you get your answer. Go start, accesories, calculator and calculate it yourself.
