2 cars are approaching each other at 40km/h. when they are 1 km apart.
\n" ); document.write( " a fly flies at 10m/s between the cars(assume it flies at the constant speed always)
\n" ); document.write( " and touches each car on it trip. How far does the fly fly when the cars crash?
\n" ); document.write( ":
\n" ); document.write( "All we have to do is find out how long it will take the cars to collide
\n" ); document.write( "That will also be how long the fly is in the air, find it's flying distance from that (d = speed * time)
\n" ); document.write( ":
\n" ); document.write( "Relative speed of two cars approaching each other at 40 km/hr = 80 km/hr
\n" ); document.write( "Time (in seconds) until they collide = $\"1%2F80\"$ * 3600 = 45 seconds
\n" ); document.write( ":
\n" ); document.write( "Fly dist = 45 * 10 = 450 meters \n" ); document.write( "

\n" );
