Answer:
625 seconds and 10 minutes
Step-by-step explanation:
distancs=S=5km=5000m
average speed=v=8m/s
time taken=t=?
as we know that
average speed=![\frac{distance covered}{time taken}](https://tex.z-dn.net/?f=%5Cfrac%7Bdistance%20covered%7D%7Btime%20taken%7D)
average speed×time taken=distance covered
here we have to find the time taken
time taken=![\frac{distance covered}{average speed}](https://tex.z-dn.net/?f=%5Cfrac%7Bdistance%20covered%7D%7Baverage%20speed%7D)
time taken=![\frac{5000m}{8m/s}](https://tex.z-dn.net/?f=%5Cfrac%7B5000m%7D%7B8m%2Fs%7D)
time taken=625seconds
now we convert seconds into minutes
![\frac{625}{60}](https://tex.z-dn.net/?f=%5Cfrac%7B625%7D%7B60%7D)
10 minutes
90• is your answer maybe If it wrong sorry
By using the linear function which models the data in the given table, the cost of a textbook with 402 pages is equal to $47.4478.
<h3>What is a scatter plot?</h3>
A scatter plot can be defined as a type of graph which is used for the graphical representation of the values of two variables, with the resulting points showing any association (correlation) between the data set.
<h3>What is a linear function?</h3>
A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.
By critically observing the graph (see attachment) which models the data in the given table, we can infer and logically deduce that the linear function is given by:
y = 0.1057x + 4.9564
If x = 402, then y is given by:
y = 0.1057(402) + 4.9564
y = 42.4914 + 4.9564
y = $47.4478.

Tricky but not crazy hard. You could use th x/y method where you turn it into a cross multiplication fiasco.
or you can try your guesses through what ever equals 1/2 when you add one to the denominator. the answer you are looking for is 2/3
2/3 + 1 for the numerator = 1.
2/3 + 1 for the denominator = 1/2.
