Radius of track = 24km = 2400m

speed = 6m/s

rounds = 3

Circumference = 2πR = 2X 22/7 x 2400

= 44/7 x 2400

Total distance = circumference x rounds = 3( 2x 22/7 x 2400)

Speed = distance/ time

6 = 3(2 x 22/7 x 2400)/ time

time (t) = 3(2 x 22/7 x 2400)/6

t = 22/7 x 2400 seconds = 7539.82237 seconds
