Final answer:
If the moon's orbital speed around the earth doubles, the number of high tides experienced in any given area will not change.
Step-by-step explanation:
If the moon's orbital speed around the earth doubles, the effect on the number of high tides experienced in any given area will not change. The number of high tides per day is primarily determined by the rotation of the Earth and the Moon's gravitational pull. Earth rotates approximately once every 24 hours, causing an observer at any given place to experience two tidal bulges (high tides) and two low tides per day.
