I think that their relative speed is \"s+-+3\" km/hr
\n" ); document.write( "where \"s\" is the speed of the car.
\n" ); document.write( "The car looks like it's going \".1%2F4\" km/min
\n" ); document.write( "or \".1%2F4\" km/min x \"60\" min/hr = \"3%2F2\" km/hr
\n" ); document.write( "\"s+-+3+=+3%2F2\"
\n" ); document.write( "\"s+=+9%2F2\"
\n" ); document.write( "The speed of the car is 4.5 km/hr
\n" ); document.write( "Hope I got it right
\n" ); document.write( "
