The formula to calculate the speed of a satellite while revolving around the Earth is given by
$v = \sqrt{\frac{G M_{e}}{R}} . . . (1)$
where, $v$ is the speed, $G$ is the Gravitational constant, $M_{e}$ is the mass of the Earth, $R$ is the radius of the orbit.
As can be seen from the equation, speed is independent of mass of satellite.
Hence, the speed of the satellites will be the same.
