The average American travels 25 minutes to and from work each day, but as many as 1.7 million Americans' work commutes take more than an hour and a half.

Quartz charted the U.S. counties with the best and worst commute times, among counties with 20,000 residents or more, using data from the U.S. Census Bureau's 2013 American Community Survey, which includes averages for 2011 to 2013. The results were surprising: Nine out of the 20 counties with the longest commutes are also on the list of the top 100 wealthiest counties in America.

Of the 20 longest commutes, many are in the Washington, D.C. area, followed by the New York City area. But the county with the longest average commute time, at 43.3 minutes, is Pennsylvania's Pike County. Among the 100 wealthiest counties, longer commutes are also frequent in the Chicago, San Francisco, and Denver areas. For the full list, head over to Quartz.
