A) 100 m
B) 200 m
C) 250 m
D) 300 m She would have to travel, at minimum, to reach the centre of the park = Radius of circular park In 15 min, she travels equal distance of perimeter of circular park Perimeter = Speed x Time \[=\frac{5\times 1000}{60\times 60}\times 15\times 60\] \[=\frac{5000}{4}=1250\] According to the question, \[2\pi r=1250\] \[\Rightarrow \,\,r=198.86\approx 200\,m\]
