The speed of the boat in still water if the speed of the current is 1.5mph is equal to 7.5mph.
<h3>Solution:</h3>
We have to define the terms in this question
We have Sc = Speed of the current = 1.5mph
We have Sb = Speed of the boat in the still water
We have this equation:
Sb + Sc = 1.5(Sb - Sc)
Sb + Sc = 1.5Sb - 1.5Sc
We have to collect the like terms
Sb - 1.5Sb = -1.5Sc - Sc
-0.5Sb = -2.5Sc
We divide through this equation by the value of Sb
![\frac{-0.5Sb}{-0.5} =\frac{-2.5Sc}{-0.5}](https://tex.z-dn.net/?f=%5Cfrac%7B-0.5Sb%7D%7B-0.5%7D%20%3D%5Cfrac%7B-2.5Sc%7D%7B-0.5%7D)
Sb = 5Sc
Given that the speed of current Sc = 1.5. then
Sb = 5*1.5
Sb = 7.5
<em>In conclusion</em><em>, the speed of the boat in still water at 1.5mph = </em><em>7.5mph</em>

A lunar eclipse happens when Earth is between the Sun and the Moon, which is a true statement about them.
When there is a lunar eclipse, the moon moves into a position where it will be in the Earth's shadow and will not be visible. This means that because the Earth sits between the sun and the moon, a shadow forms, and when the moon moves behind the Earth, the Earth prevents the moon from receiving light from the sun. If the eclipse is a total lunar eclipse, the Moon will spend roughly two hours traveling through the umbra (region of total shadow) cast by Earth. When the Moon merely passes through a portion of Earth's umbra or penumbra, a partial eclipse of the Moon occurs.
