For this case we have that by definition the time is given by:
![t=\frac{d}{v}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7Bd%7D%7Bv%7D)
Where the variable "d" represents the distance and "v" represents the speed.
So, first we need to know the total distance:
![d=(v)(t)](https://tex.z-dn.net/?f=d%3D%28v%29%28t%29)
![d=(60)(8)](https://tex.z-dn.net/?f=d%3D%2860%29%288%29)
![d=480 mi](https://tex.z-dn.net/?f=d%3D480%20mi)
Then, the time for 75mph is given by:
![t=\frac{480}{75}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B480%7D%7B75%7D)
![t=6,4](https://tex.z-dn.net/?f=t%3D6%2C4)
Answer:
6,4 hours
Answer:
x = e^2 = 7.39
Step-by-step explanation:
We have been given the logarithmic equation;
6+In x=8
The first step is to subtract 6 on both sides of the equation;
6 + ln x - 6 = 8 - 6
ln x = 2
We then introduce the exponential function, since the exponential function and the natural log function are inverses of each other;
