A runner started a course at an average speed of 6mph. Two hours later, a cyclist traveled the same course at an average speed of 12mph. How long after the runner started did the cyclist overtake the runner?
\n" ); document.write( "...
\n" ); document.write( "let x=hrs cyclist takes to overtake runner
\n" ); document.write( "travel time of runner=x
\n" ); document.write( "travel time of cyclist=x-2
\n" ); document.write( "both runner and cyclist traveled the same distance
\n" ); document.write( "distance=travel time*speed
\n" ); document.write( "6x/60=12(x-2)/60
\n" ); document.write( "6x=12x-24
\n" ); document.write( "6x=24
\n" ); document.write( "6=4 hrs
\n" ); document.write( "ans:
\n" ); document.write( "cyclist overtook the runner in 4 hrs
\n" ); document.write( "
