\n" ); document.write( "\n" ); document.write( "Police use the formula s = √30fd to estimate the speed s of a car in miles per hour, where d is the distance in feet that the car skidded and f is the coefficient of friction. If the coefficient of friction on a certain gravel road is 0.28 and a car skidded 340 feet, find the speed of the car, to the nearest mile per hour.

No, not the Pythagorean theorem.
\n" ); document.write( "Just straight substitution.
\n" ); document.write( "\"s=sqrt%2830fd%29\"
\n" ); document.write( "\"s=sqrt%2830%280.28%29%28340%29%29\"
\n" ); document.write( "Work that out with a calculator.
\n" ); document.write( "The answer is in mph.
