A person is driving at 20 m/s on a horizontal street and sees an obstacle 45 meters away in the road, so she slams on the brakes, going into a skid. The mass of the
car is 2.0 x 10^3 kg and µk = 0.44.

Question was not very clear if there are specific answer choices tell me and i'll try to you more. hope this though2 laps is 1 min. we know that for each min she does two times the amount of laps. for 12 laps we can do 12/2 which does give us 12 laps in 6 mins not 16 mins.
