It flies and hits the second train and then it starts to oscillate between the two trains. At one instance when the two trains collide it dies. Distance traveled by the fly when both trains collide is \n" ); document.write( "
Algebra.Com's Answer #290548 by mananth(16946) You can put this solution on YOUR website! distance between two trains = 60 km \n" ); document.write( "speed = 18km/h \n" ); document.write( "travelling towards each other \n" ); document.write( "so speed = 36 km/h \n" ); document.write( "... \n" ); document.write( "time to collide = 60/36= 5/3 hours.\r \n" ); document.write( "\n" ); document.write( "speed of fly = 80 km/h \n" ); document.write( "time it shuttles = 5/3 hours \n" ); document.write( "distance = speed * time = 80*5/3 \n" ); document.write( "133.33 kms \n" ); document.write( " |
