Solution for Bumblebee puzzle Incorrect The Solution given by Michael is incorrect. Since the trains are travelling in opposite direction they will meet after half an hour instead of one hour. so the distance travelled by the bee is 500 miles. since they are travelling at the same speed they will meet at the middle of the bridge =>distance =100miles. distance = speed * time;  when travelling in oppsite direction relative speed = u1+u2; 100 = (100+100) * time => time = 0.5 hour. therefore the bee travels 1000*0.5 = 500 miles.

The solutions right.. I posted it just as I was leaving for home and during the commute I realised that I screwed up and I wanted to correct it b4 anyone else saw it but You beat me to it.. Ajayshanker Krishnamurthy Monday, October 25, 2004 Of course, if you take the line that distance travelled = distance between starting point and ending point, then the answer is 100 miles +/- the length of the train...
