Problem

A geostationary satellite above the equator is orbiting around the earth at a fixed distance r1r_1 from the center of the earth. A second satellite is orbiting in the equatorial plane in the opposite direction to the earth's rotation, at a distance r2r_2 from the center of the earth, such that r1=1.21r2r_1 = 1.21r_2. The time period of the second satellite as measured from the geostationary satellite is 24p\frac{24}{p} hours. The value of pp is _____ .
