So covert 4 minutes to seconds. Which would be 4 times 60 which would mean there would be 240 seconds. So you would multiply 15 x 240 = 3,600 feet. Then multiply 22 x 240 = 5,280 feet. 5,280 - 3,600 = 1,680 feet.

The standard equation for the circle centre can be written by using this formula: (x-h)² + (y -k)² = r² 
So, the equation in this case is: (x+6)² + (y-7)² = 81
