★ᏀᏆᏙᎬΝ:-

• Time = 22 seconds.
• Radius of the circular track = 14m

Speed

★ꌗꂦ꒒ꀎ꓄ꀤꂦꈤ:-

We know that,

$\boxed{ \sf Circumference \: of \: the \: circle = 2 \pi r}$

$\sf Taking \: \pi \: as \dfrac{22}{7}$

$\text{Using the formula,}$

Distance or Circumference of the circular track =

$\boxed{ \sf 2 \times \dfrac{22}{7} \times 14}$

$\implies \sf 88m$

Now, we will find the speed.

$\boxed{ \sf Speed =\dfrac{Distance}{Time}}$

$\sf \implies Speed = \dfrac{88}{22}$

$\sf \implies Speed = {4}^{m/s}$

Hope it helps
