Police use the function f(x)=\sqrt{20} to estimate the speed of a car, f(x), in miles per hour, based on the length, x, in feet of its skid marks upon sudden braking on a dry asphalt road. A motorist is involved in an accident. A police officer measures the car's skid marks to be 84.05 feet long. Estimate the speed at which the motorist was traveling before braking. If the posted speed limit is 50 miles per hour, and the motorist tells the officer he was not speeding, should the officer believe him? Please help me
