How many times, correct to the nearest whole number, will a man run round circular track of diameter 100m to cover a distance of 1000m?
A
3
B
4
C
5
D
6
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
No. of times = \(\frac{\text{Total distance}}{\text{Circumference of circle}}\)
= \(\frac{\text{Total distance}}{\pi d}\)
= \(\frac{1000m}{\frac{22}{7} \times 100m}\)
= \(\frac{1000 \times 7}{2200} = 3.187\)
= 3(approx.) nearest whole no.
