What is the distance,in blocks , of a straight path from Xochi's home to Piero's home?

Question

Olga has two goods friends who live in her neighborhood. Xochi lives there blocks east and give blocks north of Olga. Piero lives two blocks east and four blocks south of Olga. All blocks in the neighborhood are squares. Use a coordinate grid in which Olga' s home is the origin. What is the distance,in blocks , of a straight path from Xochi's home to Piero's home?

Answer 1

Olga at (0,0)

 

Xochi at (3,5)

 

Piero at (2,-4)

 

sqrt( (-4 -5)^2 + (3-2)^1 ) = sqrt( (-9)^2 + 1^1 ) = sqrt ( 81 + 1) = sqrt(82) = 9.055

 

9 blocks north, one block east
