Question

An athletic completes one round of a circular track radius in time. What is its average speed?

Answer 1

$\huge\pink{Hello}$

Let the radius be $r$and time be $t.$

Then,

Distance travelled = Circumference of the circle.

$circumference = 2\pi r$

So,

Average speed = $\frac{2\pi r}{t}$
