One car travels 80 kilometers per hour and the other 70 kilometers per hour. At the same time, a canary, starting on one car, flies back and forth between the two cars as they approach each other. If the canary flies 90 kilometers per hour and spends no time to turn around at each car, how far has it flown when the cars collide? \n" ); document.write( "
