02) The Tennis Champion Years ago, Chris set the world record for hitting a tennis ball against a wall. She hit the ball
against the wall 60 times in 59.8 seconds, with the clock starting when the ball first hit the wall.
Billie Jean was determined to break this record. She was timed the same way Chris was, and
in her effort, Billie Jean hit the ball against the wall 60 times at a rate of 1 hit per second. Did
Billie Jean break the record, or is Chris still the champion?
