Puzzle 2

Assume that penguins live with a density of 1,000 penguins per square mile and can run at an average speed of 7 miles per hour on land and swim at 20 miles per hour. Also assume that a polar bear has a territory of 10 square miles, can run at 25 miles per hour and swim at 10 miles per hour, how many penguins will an average polar bear eat in any given month, remembering that a polar bear could, as a maximum, only eat one penguin per hour and 7% of the land is next to the sea.

Answer: None: polar bears live at the north pole and penguins live at the south pole!

Puzzle 3

A truck recently drove under my local railway bridge, it managed to get about half way when it became stuck fast.

It was too tall, 12 foot and 1 inch to be precise. The bridge was exactly 12 foot high.

The truck driver was most unhappy as his monthly bonus was stake. He tried to move backwards and then forwards, but to no avail.

Eventually a clever old soul had a marvellous idea to release the stricken truck. What was his idea?

[Ref: ZRTI]

Hint: Try to think laterally.

Answer:
He let the tyres down a little allowing the truck to complete the manoeuvre.

Puzzle 4

Traffic was bad going to work this morning. I only managed to average 30 mph.

How fast must I go home tonight, along the same route, to average 60 mph for the entire round trip?

[Ref: ZNID]

Hint: It doesn't matter what the distance is, so try a random distance.

Answer: This cannot be done.

It does not matter how far the trip is, let's assume that it is random distance, say 60 miles, and remembering that Time = Distance ÷ Speed.

The morning trip took 60 miles ÷ 30 mph = 2 hours.

To average the required 60 mph, we would have to travel the total distance (of 120 miles) in 2 hours. However, we've already used all of the two hours for the morning trip!

Choosing any random distance would also show that it can't be done.
