Which Alice?

ALICE IN PUZZLE-LAND
I'll meanwhile take a nap. Only I wants you to wake me when you're
through, you hear?"
The Gryphon then coiled himself into a perfect position for a
nap, while the Mock Turtle told Alice this old puzzle of the frog.
"One morning a frog fell into a well thirty feet deep. By day he
could climb up three feet, but each night he slipped back two feet.
How many days did it take the frog to get out of the well?"
DID HE CATCH THE TRAIN? "Now, wasn't that puzzle sad?"
asked the Mock Turtle, " — that poor frog being in the well all those
days and having to make such an arduous climb to get out!"
"Aw, shucks!" said the Gryphon, "the saddest part of that puzzle
is that I heard you the whole time and couldn't sleep nohow! Come
on, tell us another!"
"Well," said the Mock Turtle, "a man once had to go by bicycle
twelve miles to the railroad station to catch a train. He reasoned in
the following manner: 'I have an hour and a half to catch the train.
Four miles is uphill, which I must walk, and can do it four miles an
hour; there are four miles downhill, where I can coast at twelve
miles an hour; and there are four miles of level road, which I shall
do at eight miles an hour. This is an average of eight miles an hour,
so I will be just in time.' Was his reasoning correct?"
WHAT ABOUT THIS ONE? "That poor man," sobbed the Mock
Turtle, "just think — if he had been a little more clever, he could
have left earlier and made the train!
"I'm reminded of another," continued the Mock Turtle. "A train
started from a station eleven minutes late, and went at ten miles an
hour to the next station, which is one and a half miles away, and
where it stops for fourteen and a half minutes. A man reached the
first station twelve minutes after the train was scheduled to leave
and walked to the next station at four miles an hour, hoping to
catch the train there. Did he succeed?"
