plz solve it today its self . it is urgent......

Answer 1

$\text{The satellite covers a distance } 2\pi r \text{ } (r=42250 \text{ km}) = 265464.58 \text{ km}\\ \\ \text{Its speed is } v=\frac{265464.58}{24\times 60\times 60}= 3.0725 \text{ km/s}$

Answer 2

Radius is 42250km. Time taken is 24 hrs. Speed is
2 ×3.14×42250×1000÷24×60×60=3070.9m s
