Tides are coming into the shore twice as far at groves point as they are at harbor bay. compare the graphs of the length of tidal movements over time of both shorelines. a. the amplitude of the graph for harbor bay is four times the amplitude of the graph for groves point. b. the amplitude of the graph for groves point is half the amplitude of the graph for harbor bay. c. the amplitude of the graph for harbor bay is twice the amplitude of the graph for groves point. d. the amplitude of the graph for groves point is twice the amplitude of the graph for harbor bay.

Option: d is the correct answer.

d.   The amplitude of the graph for Groves Point is twice the amplitude of the graph for Harbor Bay.

It is given that:

Tides are coming into the shore twice as far at Groves Point as they are at Harbor Bay.

This means that when we plot the graph of both the points then the amplitude will represent the maximum distance that is traveled by a tide now as the tides in the Groves point are coming twice as far this means that the amplitude will also get doubled.

   Hence, the statement that Compare the graphs of the length of tidal movements over time of both shorelines is:

                      Option: d

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
