Answer:

  12 miles

Step-by-step explanation:

The diagonal distance from Raymond's house to Lucky's house is given by the Pythagorean theorem as ...

  c = √(a² +b²) . . . . . where c is the hypotenuse length of a right triangle with legs "a" and "b"

Here, we have a=4, b=3, so ...

  c = √(4²+3²) = √(16+9) = √25 = 5 . . . . miles

So, Raymond's trip that day was ...

  distance to Raymond's + distance from Raymond's to Lucky's + distance from Lucky's

  = 4 + 5 + 3 = 12 . . . . miles
