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.

Four members of a band
Four members of a band are walking to a night concert. They decide to take a shortcut, but must cross a bridge. Luckily they have one flashlight. Because of the varying size of their instruments, it takes each member a different amount of time to cross the bridge - it takes the first person one minute, the second person two minutes, the third person five minutes and the fourth person ten minutes.
They must cross the bridge in pairs, travelling at the slower speed so if the one minute person went with the ten minute person, it would take a total of ten minutes. Since there is only one flashlight, one person must come back across the bridge, then another pair can cross. They only have 17 minutes to cross the bridge and still get to the concert on time. What order should they cross to get everyone across and get to the concert?
