BREAKING NEWS!

A Mars probe sent from Earth has disturbed a colony of Martians. They have come to Earth and have taken over our planet. The Martian leader has decided to change the unit of length used in the United States from 12 inches in a foot to 10 inches in a foot because the Martian's foot is only 10 inches long.

The Martians are allowing the United States to keep the mile the same length as before so that no new road signs and mile markers have to be created. Now that the Martians have taken over our planet, how many feet are in one mile?

### Hint

In the original mile there are 5,280 feet.### Answer

6,336 feet.In the original mile there are 5,280 feet. That means that there were 63,360 inches in a mile (5,280x12).

There are still 63,360 inches in a mile because the inches and overall length of the mile are unchanged. Because there are 10 inches in a foot, divide 63,360 by 10. This will give you the new amount of feet in a mile--6,336!
