distance = 500m
\n" ); document.write( "speed = 10 kph
\n" ); document.write( "(10*1000)/3600 m/s ( 1 km = 1000 m, 1 hour = 3600 sec)
\n" ); document.write( "=2.7 m/s
\n" ); document.write( "t= d/s
\n" ); document.write( "500/2.7
\n" ); document.write( "= 185 seconds
\n" ); document.write( "Ali takes 185 s for a lap
\n" ); document.write( "
