What is the difference between an apex and a late apex, and how does each affect exit speed?

• A. The apex is the geometric center of the turn; a late apex places the turning point later, enabling earlier throttle and higher exit speed.

• C. A late apex slows exit speed; the apex requires accelerating early.
• D. The apex and late apex are the same concept; they do not affect exit speed.
