I hope you want the time taken to finish a 5 km race. Based on this i am solving the problem given.
Amount of time required to jog 2 kilometers = 12 minutes
Then
Amount of time required to jog 1 kilometer = (12/2) minutes
= 6 minutes
So
Amount of time required to jog 5 kilometers = (6 * 5) minutes
= 30 minutes
So it will take 30 minutes to finish a 5 kilometer race.
I hope the procedure is clear to you.
Equation of circle
(x-h)^2 + (y-k)^2 = r^2
I believe it is
(x-2)^2 + (y+2)^2 = 16
