Rona was driving on an asphalt road that had a 35 mi/h speed limit posted. A deer jumped out from the side of the road causing Rona to slam on her brakes. Her tires left three skid marks of lengths 70 ft, 72 ft, and 71 ft. The road had a drag factor of 0.78. Her brakes were operating at 95% efficiency. The police gave Rona a ticket for speeding. Rona insisted that she was driving under the limit. Who is correct (the police or Rona)? Show your work.
