Question

An athlete completes one round of a circular track of diameter
200 m in 40 s. What will be the distance covered at the end of 2 minutes 20 s?

Answer 1

Given-

• Diameter of a circular track =200m

$\large{ \implies{so \: radius = \frac{200}{2} = 100m}}$

$\huge{ \purple{ \texttt{SOLUTION:-}}}$

Circumference of circle =2πr = 2×22/7×100

$\large \implies{ \frac{4400}{7} }$

Time for which the athlete ran = 2 min 30sec

Therefore,

Distance covered by athlete -

$\large \implies{ \frac{4400}{7} \times \frac{140}{40} }$

$\large \implies{2200m}$

$\small{ \boxed{ \blue{ \mathtt{ Distance \: covered \: by \: athlete = 2200m}}}}$
