About how fast does a meteorite travel?

From "Introductory Astronomy and Astrophysics" by Smith and Jacobs: (note that meteorites are meteoroids that have entered the earth's atmosphere) "Solar escape speed at the Earth's orbit is 42 km/sec; meteoroids cannot move faster than this. In the early evening, meteoroids must catch the Earth, while after midnight, the Earth (30 m/sec) catches up to all but the fastest meteoroids moving along its orbit." Conversion of km/sec to MPH is left as an exercise for the reader.
