A) \[0,1\]
B) \[\frac{\pi +4}{2},0\]
C) \[21.4,\frac{\pi +4}{2}\]
D) \[0,21.4\]
Correct Answer: D
Solution :
Since, the initial position of cyclist coincides with final position, so his net displacement I zero. Average speed \[=\frac{total\text{ }distance\text{ }travelled}{total\text{ }time\text{ }taken}\] \[=\frac{OP+PQ+QO}{10}km/\min \]. \[=\frac{1+\frac{\pi }{2}\times 1+1}{10}km/\min \] \[=\frac{\pi +4}{20}\times 60\,km/\min \] \[=21.4\,km/h\]You need to login to perform this action.
