Answer 2

Answer:-

$★\text{Diameter = 200m}$

$★\text{Radius = D/2 = 100m}$

$★\text{Time = 40 Seconds}$

$★\text{Speed = D/T}$

$★\text{Circumference = 2} \pi \: r$

$★\text{20 mint 20 sec = 140 \: seconds}$

$★\text{Number of Round = 140/4 = 35}$

$⇒\text{Distance Covered = 35} \times 2\pi \: r$

$⇒35 \times 2 \times \frac{22}{7} \times 100$

$⇒5 \times 2 \times 22 \times 100$

$\textbf{Distance Covered = 22000m}$

Hence,

• The distance covered at the of 2min20 seconds in 22000m OR 200m.
