-converting to a common denominator
The terms -c of the left side was converted to -4ac/4a to have the same denominator of b^2/4a.
circumference is C = πd, d = diameter.
we know the diameter is 60, so one time around the track is just C = π60 which if you plug that in your calculator, we get C ≈ 188.4955592153876.
It will take him 240 min and if u convert that it will take him 4 hours
