Bringing back the old thread I've never heard of before.

Okay, let's start:

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?

The clock was on time but the train's speedometer was 25% off.

The answer is a bit more complicated then that.

You need to know your maths.

I know my maths and I know that the train left five minutes late.

Did the first train take 65 minutes to complete a one hour journey or should the journey have only taken 55 minutes but took an hour? Which station clock are we talking about?

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.

Yup, because once you subtract 5, you'll be subtracting from 20.

What grade are you in?

As many times as you like. You will get the answer "20" each time.

The other one is an arrow. A spear may be thown.
