The value of
is ![\frac{27}{35}](https://tex.z-dn.net/?f=%5Cfrac%7B27%7D%7B35%7D)
Explanation:
Given that
and ![g(x)=7x](https://tex.z-dn.net/?f=g%28x%29%3D7x)
<u>The value of </u>
<u>:</u>
The value of
can be determined by substituting x = 5 in the functions f(x) and g(x) and then dividing the terms, we get, the value of ![(\frac{f}{g})(5)](https://tex.z-dn.net/?f=%28%5Cfrac%7Bf%7D%7Bg%7D%29%285%29)
Thus, we have,
![(\frac{f}{g})(5)=\frac{f(5)}{g(5)}](https://tex.z-dn.net/?f=%28%5Cfrac%7Bf%7D%7Bg%7D%29%285%29%3D%5Cfrac%7Bf%285%29%7D%7Bg%285%29%7D)
Substituting the value of x = 5 in the functions f(x) and g(x), we get,
![(\frac{f}{g})(5)=\frac{7+4(5)}{7(5)}](https://tex.z-dn.net/?f=%28%5Cfrac%7Bf%7D%7Bg%7D%29%285%29%3D%5Cfrac%7B7%2B4%285%29%7D%7B7%285%29%7D)
Simplifying the terms, we have,
![(\frac{f}{g})(5)=\frac{7+20}{35}](https://tex.z-dn.net/?f=%28%5Cfrac%7Bf%7D%7Bg%7D%29%285%29%3D%5Cfrac%7B7%2B20%7D%7B35%7D)
Adding the terms in numerator, we have,
![(\frac{f}{g})(5)=\frac{27}{35}](https://tex.z-dn.net/?f=%28%5Cfrac%7Bf%7D%7Bg%7D%29%285%29%3D%5Cfrac%7B27%7D%7B35%7D)
Thus, the value of
is ![\frac{27}{35}](https://tex.z-dn.net/?f=%5Cfrac%7B27%7D%7B35%7D)
Divide the speed in kmph by 1.6 to get miles per hour.
110 / 1.6 = 68.75 miles per hour
Multiply the speed by the time.
68.75 x 5 = 343.75 miles in 5 hours.
