Back Question 1 Not yet answered Marked out of 1,00 \\'7 Flag question Time left 1:55:44 The diagram below is the 400 m oval for long-track speed skating, where athletes must skate one lap to complete the race. The skaters end the race at the same place they begin the race. Start/End When this athlete completes the 400 m race, her displacement from he starting point is C] A. 0 m B. 200 m C. 400 m D. dependant on how fast she skates.
