Step-by-step explanation:
During the Boston Marathon, a What are the unit rates for this situation? (How far can they run in 1 hour and how long does it take to run 1 mile?)
If a certain runner averages running 25 miles in 5 hours, then
25miles = 5hrs
To determine how far they can run in 1 hour, then;
X = 1hr
Divide both expressions
25/x = 5/1
5x = 25
X = 5miles
Hence the runner can run 5miles in an hour
Similarly if
25miles =1hr
1mile = y
25y = 1
Y = 1/25
Y = 0.04hrs
Hence the time taken to run 1mile is 0.04hrs
You can tell when a pattern is counting on by 10s when the pattern has a number and 0s at the end
Rearrange the given equation in slope intercept form
![y = \frac{3x - 1}{ - 2} \\ y = - \frac{3}{2} x + \frac{1}{2}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B3x%20-%201%7D%7B%20-%202%7D%20%20%5C%5C%20y%20%3D%20%20-%20%20%5Cfrac%7B3%7D%7B2%7D%20%20x%20%2B%20%20%5Cfrac%7B1%7D%7B2%7D%20%20)
slope of the required line is
![- \frac{1}{ - \frac{3}{2} } = \frac{2}{3}](https://tex.z-dn.net/?f=%20-%20%20%5Cfrac%7B1%7D%7B%20%20-%20%5Cfrac%7B3%7D%7B2%7D%20%7D%20%20%3D%20%20%5Cfrac%7B2%7D%7B3%7D%20)
equation is given by
In the picture we can see one whole square and 1/4 of a whole square shaded this means that 1 1/4 or 5/4 would be appropriate answers but it says that you are trying to find a appropriate mixed number. A mixed number is a number that includes a whole number and a fraction. For example, 3 1/3 is a mixed number. This means that it can't be 5/4 because it doesn't include a whole number leaving 1 1/4. So, 1 1/4 or D would be correct.
