Answer 2

$\mathit{\large{\red{\underline{\underline{Answer:-}}}}}$

$\textbf{\large{\pink{\underline{Step by step Explanation:-}}}}$

$\mathcal{\underline{Given,,}}$

$\mathtt{diameter(d)=14m}$

$\mathcal{\underline{Hence,,}}$

$\mathtt{redius(r)=\frac{d}{2}}$

$\mathtt{\implies{\frac{14}{2}}}$

$\mathtt{\implies{7m}}$

$\mathcal{\underline{And,,}}$

$\mathtt{perimeter=2\pi{r}}$

$\mathtt{\implies{2\times{\frac{22}{7}}\times{7}}}$

$\mathtt{\implies{44m}}$

$\mathcal{\underline{Hence,,}}$

$\textit{athlete completes one round(44m) of the circular track in 20 seconds}$

$\mathtt{speed=\frac{distance}{time}}$

$\mathtt{\implies{\frac{44m}{20}}}$

$\mathtt{\implies{2.2m/sec}}$

$\textit{athlete runs 2.2m in a sec}$

$\textit{then,,in 2 minutes 10 seconds(130 seconds) the distance covered by athlete= }$

$\mathtt{\implies{speed\times{time}}}$

$\mathtt{\implies{2.2m\times{130}}}$

$\mathtt{\implies{286m}}$
