Slow speech is usually regarded as less than 110 wpm, or words per minute. Conversational speech generally falls between 120 wpm at the slow end, to 160 - 200 wpm in the fast range. People who read books for radio or podcasts are often asked to speak at 150-160 wpm.
Although a college degree is required for many teaching in early education, it's not unusual for a teacher to get about $11.75 an hour or $24,440 for the year. That salary puts a family of three or more below the federal poverty line. The state minimum wage now stands at $9 an hour and will rise to $10 in 2016.
The Bureau of Labor Statistics reports that the average pre-school teacher in the U.S. earns an hourly wage of $14.50. Pre-school teachers in the McAllen, Edinburg and Mission areas of Texas are the best paid, with average hourly wages of $24.23.
