Pennies
Someone offered Mad Ade a choice between a ton of pennies and five miles of pennies lined up with touching edges. Which should Mad Ade take if he wanted the most money? Here are some facts to help you decide: A penny weighs .09 ounces. A penny's diameter is .75 inches.
Answer
Five miles of pennies are worth more than the ton of pennies.Use a calculator to find the inches in a mile, then 5 miles. 316,800 inches divided by .75 inches = 422,400 pennies, or £4,224.
1 ton = 32,000 ounces divided by .09 ounces = 355,555.55 pennies, or £3,555.56.
