Find the rate of speed of a car that left a 150 feet skid mark. Round to the nearest whole number and solve the formula for L.
\n" ); document.write( "r=2√5*L
\n" ); document.write( "---
\n" ); document.write( "L = r/(2sqrt(5)
\n" ); document.write( "L = 150/(2sqrt(5)
\n" ); document.write( "L = 75/sqrt(5
\n" ); document.write( "L = 75*sqrt(5)/5
\n" ); document.write( "L = 15*(sqrt(5))
\n" ); document.write( "L is approximately 33 mph\r
