erbian tennis player Bojana Jovanovski
was only 19 when she played in the
San Diego Open. However, she very
nearly missed the tournament. Her first match
was in Carlsbad, California, so her agent
booked a seat for her and gave her the ticket
to Carlsbad. It was a long journey because
Bojana needed to take three different planes.
When she finally arrived in Carlsbad, she was surprised
to find that the airport was empty. She waited for 15 minutes
and then called Tournament Transport. The problem was that Bojana was
in Carlsbad, New Mexico and the transport service was in Carlsbad,
California where the tournament was. So, Bojana stayed in New Mexico for
the night and then travelled to Carlsbad, California the next morning. She
arrived only 30 minutes before the start of her match with the Italian player
Roberta Vinci. Unfortunately, the day finished badly for Bojana because
she lost the match 3-6, 6-4, 6-1. After that, she just wanted to go home!4 задание помогите Хэлп вопросы ответить
