Police use the formula: v = 20L to estimate the speed of a car, v, in miles per hour, based on the length, L, in feet, of its skid mark- when suddenly braking on a dry, asphalt road. At the scene of an accident, a police officer measure a car's skid marks to be 100 feet long. Approximately how fast was the car traveling? Round your answer to the nearest tenth (one decimal place) of a unit. Answer: The car was traveling at approximately miles per hour.
