Answer:

3 minutes

Step-by-step explanation:

d=3t is our formula.

d being the distance (9 inches for this problem)

t is the time in minutes


Substituting our known information would make our equation look like:

9 = 3t

to solve for t we divide both sides of the equation by 3

9/3 = 3t/3

3 = t


So if a snail travels 3 inches per minute, it will have traveled 9 inches in 3 minutes.

What is the median of this set of data: 593, 588, 540, 434, 420, 398, 390, 375
Aleks04 [339]

<u>Answer:</u>

<u><em>426</em></u>

<u />

<u>Explanation:</u>

To find the median number in a set of data start by reordering the data from least to greatest.

<em>original data set:</em>

<em>593, 588, 540, 434, 420, 398, 390, 375</em>

<em />

<em>data set from least to greatest:</em>

<em>375, 390, 398, 420, 434, 540, 588, 593</em>

<em />

Next, you would usually just have to find the middle number in the data set and that would be your median. However, this data set has no one number that is directly in the middle. So, we will add both middle numbers together and then divide our answer by two.

<em>375, 390, 398, </em><em>420, 434</em><em>, 540, 588, 593</em>

<em />

<em>420 + 434 = 854</em>

<em />

<em>854 ÷ 2 = 426</em>

<em />

Therefore, the median of the given data set is <em><u>426.</u></em>
