Answer:
The speed is still water is 
.
Step-by-step explanation:
Dimentionally speaking, speed is distance divided by time. Since, the person is travelling downstream, absolute speed is equal to the sum of current speed and speed of the person regarding current. Both components are constant. That is:
Where:
- Current speed, measured in miles per hour.
- Speed of the person regarding current, measured in miles per hour.
- Distance travelled downstream, measured in miles.
- Time spent on travelling, measured in hours.
Speed in still water occurs when current speed is zero. Then, such variable is obtained after subtracting current speed on both sides of the expression. Hence:
The speed is still water is .

Matter exists in three states; <em>solid, liquid and gas.</em>
The statement that corrects the error in his table is:
<em>D. The Solids column and the gas column should be switched because solids have a definite shape and volume and gases have no definite shape or volume.
</em>
<em />
<em />
Looking at the table, we have the following observations.
- <em>The solid column shows indefinite shape (because the particles fill in the container)</em>
- <em>The liquid column is properly cataloged</em>
- <em>The gas column shows a definite shape</em>
<em />
Solid has definite shape, while gas doesn't.
To make corrections, Marcus needs to switch the gas and the solid column.

Answer:
<em>It takes them 1.875 hours.</em>
<em></em>
<em>Step-by-step explanation:</em>
<em></em>
<em>Here, the job is cleaning the house.</em>
<em></em>
<em>Mom does 1 job in 3 hours.</em>
<em></em>
<em>In 1 hour, mom does 1/3 of the job.</em>
<em></em>
<em>Dad does 1 job in 5 hours.</em>
<em></em>
<em>In 1 hour, dad does 1/5 of the job.</em>
<em></em>
<em>Mom and dad working together do the job in x hours.</em>
<em></em>
<em>In 1 hour, mom and dad together do 1/x of the job.</em>
<em></em>
<em>1/3 + 1/5 = 1/x</em>
<em></em>
<em>5/15 + 3/15 = 1/x</em>
<em></em>
<em>8/15 = 1/x</em>
<em></em>
<em>8x = 15</em>
<em></em>
<em>x = 15/8 = 1.875</em>
<em></em>
<em>Answer: It takes them 1.875 hours.</em>
