Answer
Train
Journey
Mr.
Grumper grumbles about bad time-keeping
trains like everybody else. On one particular
morning he was justified, though. The train
left on time for the one hour journey and
it arrived 5 minutes late. However, Mr.
Grumper's watch showed it to be 3 minutes
early, so he adjusted his watch by putting
it forward 3 minutes.
His watch kept time during the day, and
on the return journey in the evening the
train started on time, according to his
watch, and arrived on time, according to
the station clock.
If the train traveled 25 percent faster
on the return journey than it did on the
morning journey, was the station clock fast
or slow, and by how much.
» ANSWER
The station clock is 3 minutes fast. The morning journey took 65 minutes, and the evening journey therefore took 52 minutes, and the train arrived 57 minutes after it should have left, that is, 3 minutes early. |
