Here is your answer !!

________

A cyclist go around circular track ones in every 2mins .if the radius of circular track is 105 km.

Since radius is 105 km ,
cirvumference is 2πr km
= 2 × 22/7 × 105 km
= 660 km .
= 660000 m.

Time taken to go round the track = 2 min = 2 * 60 secs = 120 secs .

So , speed of the cyclist = 660000 m / 120 s
= 5500 m / s . [ Answer ] .
