First, we need to convert the time from minutes to hours by dividing by 60: 12 minutes / 60 minutes/hour = <<12/60=0.2>>0.2 hours
Next, we divide the total distance traveled (4 laps * 1 mile per lap = <<4*1=4>>4 miles) by the time it took to travel that distance to find the average speed: 4 miles / 0.2 hours = <<4/0.2=20>>20 miles per hour. Answer: \boxed{20}.
Blake has entered a mountain bike competition at Starvation Flats Bike Park. Placement in the competition is determined by a person's average speed over four laps around the course. The course itself is of a mile long. If Blake completed the four laps in 12 minutes, then his average speed around the track is
