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 is zero. Average speed \[\text{=}\frac{\text{total distance travelled}}{\text{total time taken}}\] \[\text{=}\frac{OP+PQ+QO}{10}km/\min .\] \[=\frac{\text{1+}\frac{\pi }{2}\times 1+1}{10}km/\min \] \[=\frac{\pi +4}{20}\times 60\,km/h\] \[=2.14km/h\]You need to login to perform this action.
