The distance between first base and second base is 90 feet.
It's 127 feet, 3 3/8 inches from home plate to second base (the same distance from first base to third base).
A base line is 90 feet long, so (since you have to go around third to get home from second) the total distance is 270 feet.

The distance from home plate to first base is 90 feet and the distance from first base to second base is also 90 feet making a right angle; you can calculate how far the catcher needs to throw to 2nd base from home by Pythagorean theorem. Answer is 127.3 feet

If the pitcher is not on the pitcher's plate, he can turn as far as he wants to look at the runner on first base. If the pitcher is on the pitcher's plate, and his shoulder turns more than 45 degrees toward first base (halfway between home and first), it is generally interpreted to be a pick-off attempt.
It takes him 3.93 sec. for him to get from home plate to first base.
