This problem can be seen as a rectangle triangle where the vertices are: Vertice 1: home plate Vertice 2: First base Vertice 3: second base. Right angle between vertice 1 and 2 and vertice 2 and 3. Distance between each base in 90 '. Calculating then the distance between home plate and second base we have: d = root ((90) ^ 2 + (90) ^ 2) d = 127.28 feets answer: the distance between home plate and second base is 127.28 feets
