How much it costs depends on where and when you start

Price of a taxi ride ranges from $0.91 off-peak in Dehli to $24.24 at peak time in Zurich. See World taxi prices: What a 3-kilometer ride costs in 72 big cities.
It's interesting that this information isn't available on the web for Worcester. Although the ordinances of the city state that the city council can set the rates, the rates aren't published in a manner that civilians can find them. For example, what would be the cost of a ride from WCUW to the Worcester Art Museum, about two miles or just a bit more than 3km?
