Question

give an expression for a speed of an athlete , if he takes time T to go around the circular track of radius R

please no spamming

it's urgent

Answer 1

we have,
radius of circular track = R
time taken = T
total distance travelled = circumference of the circular track
= 2×pi×R

now,
speed = total distance travelled / time taken
= (2×pi×R)/T
therefore speed = (2×pi×R)/T
