■ Correction: Because of a graphic designer’s error, a graphic in Sunday’s Sports section on Usain Bolt incorrectly stated the distance at which Bolt achieves maximum speed during the 100-meter dash. He achieves maximum speed between 50 and 60 meters.

■ Correction: Because of a reporting error, an article in Saturday’s paper about the state Supreme Judicial Court incorrectly listed the age of retired Justice Fernande R.V. Duffly. She is 66.
