Mr. Moody grumbles about bad time-keeping trains from morning till night!.
one particular morning he was quiet justified.
train left on time for the one hour journey, to Clarksville, and it arrived
5 minutes late.
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.
the train travelled 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?
