I want to know the answer to the following question:
What is the average wind speed in miles per hour for St. John's?
All the background I'm provided with is that "Of major Canadian cities, St. John's is the foggiest (124 days), windiest (24.3 km/h (15.1 mph) average speed), and cloudiest (1,497 hours of sunshine).". Is that enough to answer the question?
