A man went down a flight of stairs by walking a few steps and
running 14 steps, taking a total of 41s. He repeated this by
walking a few steps and running 6 steps, taking 65s to do so. What
would be time taken if he only walked down the flight of
stairs?
If the "few steps" are not the same, then I think it is
impossible to pin down an answer.
isn't 83s the time taken to complete all the steps by walking??
