458. Fuel Consumption

A car travelled from London at a speed of 40mph. Its fuel consumption was 30 mpg.
It had a 5 gallon tank which was full when it started, but at that very moment
began to leak fuel. After 60 miles the car stopped with a completely empty tank.
How many gallons per hour was it losing?

Solution

2 gallons per hour.

The car travelled 60 miles before stopping, this means it used 2 gallons. The car took 1.5 hours to travel 60 miles.
Therefore the car lost 3 gallons in 1.5 hours = 2 gallons per hour.

455. Old Man Wrinkle

Old Man Wrinkle spent one-fourth of his life as a boy, one-eighth as a youth, and one-half as an active man.
If Man Wrinkle spent 12 years as an old man, then how many years did he spend as an active man?

Solution

He spent 48 years as an active man.

Fraction of life as a boy = 1/4
Fraction of life as a youth = 1/8
Fraction of life as an active man = 1/2
Fraction of life as boy, youth and active man = 1/4 + 1/8 + 1/2 = (2 + 1 + 4)/8 = 7/8
Fraction of life as an old man = 1 - 7/8 = 1/8
Thus, one-eighth of Man Wrinkle's life (as an old man) is 12 years.
So, Man Wrinkle's Age = 96 years.

Life as active man = 96/2 = 48 years.

454. Of Penguins and Polar Bears

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?

Solution

None. Penguins live at the South Pole and polar bears live at the North Pole.

451. Hotel Security

A woman was sitting in her hotel room when there was a knock at the door.
She opened the door to see a man whom she had never seen before. He said,
"Oh I'm sorry. I have made a mistake. I thought this was my room." He then
went off down the corridor to the elevator. The woman went back into her
room and phoned security to have the man apprehended. What made the woman
so suspicious of the man?

Solution

If it were his own room, he would have had a key and would not have knocked.
