Four friends live at the four corners of a rectangular block. Jose lives 3 miles away from Ana. How far is Pedro's house from Rosa's?

Question

Its so hard to answer it thats why i need a answer

 

Answer 1

Draw a picture !!

 

If Jose and Ana live closest to each other --

 

   Jose                                    Ana

   + - - - - - - 3 mi - - - - - - - - - +

   |                                            |

   |                                            |

   + - - - - - - - - - - - - - - - - - - - +

   X                                            Y    (X and Y are Pedro and Rosa, in either order)

 

Or, if Jose and Ana live furthest from each other, it could be:

 

    Jose                               X
     + - - - - - - -- - - - - - - - - +
     |    \                              |
     |    3 mi diagonal       |

     |                              \   |

     + - - - - - - - - - - - - - - - +

    Y                                  Ana   (X and Y are Pedro and Rosa, in either order)

 

"Four friends live at the four corners of a rectangular block." means that you have the distance between two of those friends.  And, since they live on the corners of a rectangle (not parallelogram), the distance between the other two friends is exactly the same.

 

That's bercause:

    "opposite sides of a rectangle are the same length"

    "the two diagonals of a rectangle are the same length"

 

 

 

Extra information to consider:  When playing Tic-Tac-Toe, there are only three possible first moves (center, side, corner  -- PLZ rotate and invert as needed).  This significantly reduces the tree diagram of the moves.

Answer 2

it's not possible to determine an answer because you don't know whether Jose and Ana constitute a side, or whether Jose and Ana constitute a diagonal of the rectangle.  If, the diagonal, more information is required.  If, one side, then the distance between Jose and Ana, 3 miles, is also the distance between Pedro and Rosa.
