Traffic accident investigators use the formula: 

 

\( v = \sqrt { 24 L } \) 

 

to estimate the speed of a car, \( v \) , in miles per hour, based on the length, \( L \) , in feet, of its skid marks when suddenly braking on a flat, dry, asphalt road. 

 

At the scene of an accident, a car's skid marks are measured to be \( 163 \) feet long. Approximately how fast was the car traveling? Round your answer to the nearest tenth.
