25 laps in 6 hrs Number laps/time=rate 25 laps/6 hrs=4.1667 laps/hr
\n" ); document.write( "Or for time per lap 1 lap=1 hr/4.1667 laps=0.24 hrs/lap
\n" ); document.write( "Convert to minutes/lap:(0.24 hrs/lap)(60 min/hr)= 14.4 min/lap
\n" ); document.write( "Number of laps times time/lap=total time (60 laps)(0.24 hrs/lap)=14.4 hr
\n" ); document.write( "OR
\n" ); document.write( "For the above problem, let T=total time
\n" ); document.write( " $\"25+laps%2F6+hrs=60+laps%2FT\"$ Multiply each side by T
\n" ); document.write( " $\"%2825+laps%2AT%29%2F6+hrs=60+laps\"$ Multiply each side by 6 hrs
\n" ); document.write( " $\"25+laps%2AT=360+lap-hrs\"$ Divide each side by 25 laps
\n" ); document.write( " $\"T=360%2F25+hrs\"$ =(14.4 hr)
\n" ); document.write( " \r
