Tidal power plants work best in small estuaries or inlets that border the ocean. true or false?

True

Step-by-step explanation:

The tidal ranges will be more pronounced in small estuaries and inlets because more tidal volume of water per unit area will move in and out of a small basin than a big basin (hence higher potential difference). This way more energy can be harnessed by the turbines as the tide flows in and out of the estuary/inlet.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
