Consider an artificial satellite moving around the Moon in an elliptic orbit. The
altitude of the satellite from the Moon's surface at the perigee is 25 km and that at
the apogee is 134 km. Assume the Moon to be spherical with a radius of 1737 km.
The trajectory is considered with reference to a coordinate system fixed to the center
of mass of the Moon. The ratio of the speed of the satellite at the perigee to th at at
the apogee is ___________ (rounded off to 2 decimal places).
