Answer:
40 m
Explanation:
Radius = 100 m
number of rounds he takes = 2 1/2
Total distance covered by him = 100 ÷ 2.5
= 40 m
Answer:
radius of circular ground= 100 m
perimeter of circle = 2πr
so, 2*22/7*100
=4400/7m
he covered two and half round ,so-
4400/70 * 5/2
= 11,000 metre
hence he covered 11000/7 metre
