A satellite

\text{S}_1

is in a circular orbit

300\,\text{km}

above Earth’s surface and takes

90\,\text{min}

to complete one revolution. Another satellite

\text{S}_2

is in a circular orbit

1\,500\,\text{km}

above Earth’s surface. Calculate, to the nearest minute, the time taken by

\text{S}_2

to complete one revolution. Use

R_{\rm E}=6.4\times10^{6}\,\text{m}
