1 км = 1000 м
60 м = 0,06 км
1 ч = 3600 сек
1 с = 1/3600  ч
2 с = 2/3600 = 1/1800 ч
V = 0, 06 км * 1800 ч = 108 км/ч

Ответ: Превысил.

EXAMINATION AND FUNCTIONS OF DOCTOR
Before the treatment of a disease an attending doctor should establish a diagnosis. It is necessary for a doctor to determine the etiology of the disease, pathogenesis and symptoms, signs by which it can be revealed.
A number of different procedures are used to make a diagnosis. They are: history-taking, physical examination, palpation, percussion, auscultation (выслушивание), laboratory studies, and instrumental studies.
The attending doctor must know objective and subjective symptoms and complaints of patients as well as how long sick people have been having these symptoms.
History of present illness makes a part on a case history (=case report). The history of present illness contains a lot of findings: information of the patient on his admission, the results of laboratory and instrumental tests, and the course of disease with any changes in the symptoms and condition, the exact doses of the prescribed medicines, the produced effects of treatment. The case history should be written in a correct way, it should contain the exact and complete information.
