Winning at Wimbledon

As a result of temporary magical powers, you have made it to the Wimbledon finals and are playing Roger Federer for all the marbles. However, your powers cannot last the whole match. What score do you want it to be when they disappear, to maximize your chances of hanging on for a win?

It sounds obvious that you should ask to be ahead two sets to love (it takes 3 out of 5 sets to win
the men’s), and in the third set, ahead 5-0 in games and 40-love in the sixth game. (Probably you
want to be serving, but if your serve is like mine, you might prefer Roger to be serving the sixth
game down 0-40 so that you can pray for a double fault.)

Not so fast! These solutions give you essentially 3 chances to get lucky and win, but you can
get six chances—with three services by you and three by Roger. You still want to be up two sets
to none, but let the game score be 6-6 in the third set and 6-0—in your favor, of course—in the
tiebreaker.

The Train and the Tunnel

A train is a half mile long and is about to enter a 10 mile tunnel. If the train is traveling at 35mph, how long will it take for the entire train to make it through the tunnel, from the front of the train entering to the end of the train leaving the tunnel?

18 minutes.

Length of the train: 0.5 miles
Length of the tunnel: 10 miles
Total distance: 0.5 + 10 = 10.5 miles

Time = 10.5 miles / 35 mph = 0.3 hours = 18 minutes

How Old is Lilly?

Two days ago Lilly was 7 years old. Next year she will turn 10. How can this be?

Her birthday is December 31st. Today is January 1st so she was 7 two days ago, and turned 7 last year. Now she’s 8 and will turn 9 this year. And next year she’ll turn 10.

For example, if today is 01 Jan 2015:

30 Dec 2014 = age 7 (two days ago)
01 Jan 2015 = age 8 (today, she turned 8 on 31 Dec 2014, which was last year)
31 Dec 2015 = age 9 (her birthday this year)
31 Dec 2016 = age 10 (her birthday next year)

I Stand Like A Sentry

I stand like a sentry
And am barred by the gentry,
The first month and its god oft slip
Between my hard, dun colored lip.

What am I?

Sentries are posted at borders, gates, or doors.
The gentry (in this case to referring to the general populace) bar their doors at night.
The first month is January, named after the Roman god Janus, the double-faced God of doorways, passages and thresholds.
You pass through the doorway (hence the slip), and dun is a brown color, referencing the color of wood, which most doors are made of. Though it’s not commonly referred to, the “lip of the door” is the part of the door that fits into the doorframe on the handle/knob side, particularly if the door is lipped or ridged in order to fit the door frame better.
