Do you remember them? The story went something like this:
A set out for B’s house, three miles away, at d miles an hour. B set out for A’s house at the same time, at e miles an hour. State the formulae for calculating the time t minutes before they meet, and the position of the point p where this occurs.
They talked for five minutes, then headed for B’s house at f miles an hour. Meanwhile, five minutes after they started out, C set out for B’s house at g miles an hour. State the formula… And so on…
This post was prompted by the ‘100 word challenge’ here.
It is based on some memories of long ago!
