What is the time interval between two successive tides at a given place on the earth?

What is the phase difference between two successive crests in the wave

A satellite having time period of revolution 6830 sec is travelling in the same direction as the rotation of the earth, i.e. from west to east, the time interval between the two successive times at which it will appear vertically overhead to an observer at a fixed point on the equator is

If a satellite is travelling in the same direction as the rotation of earth i.e., west to east, what is the interval between two successive times at which it will appear vertically overhead to an observer at a fixed point on the equator? (R = 6400 km, h = 1400 km)

Find the following : The time period of a wave if the time interval between 1st crest and 9th crest is 48 s
