A Conundrum.
A train leaves a station at 64 mph, travels 230.4 miles and crashes into the buffers at the end.
As the train leaves the station a super fly sat on the buffers sets off at 93 mph, touches the buffers at the other end turns round and races back to the train, touches the train’s buffers turns round and races back and forth until it is squashed between the train and the buffers down the line.
The question is, how far did the fly, fly before being squashed?
This is a theoretical question so please no comments about flies not being able to fly at those speeds nor turn around instantly etc. It’s a simple question that was asked in a school exam 54 years ago. The actual figures may be different to what they were then but otherwise the question is essentially the same.
If you get an answer can you tell us how you got it?
