Answer: 5.3 Hours
Step-by-step explanation: 140 mi there at 56 mi per hour would be 2.5 hours. Then back 140 mi at 50 mi/h would be 2.8. 2.5 plus a 2.8 is 5.3 hours

The answer is 18 cups. 8fl=1cup. 144/8=18cups
Answer:
![P(X](https://tex.z-dn.net/?f=%20P%28X%3C3.7%29)
And we can use the cumulative distribution function given by:
![F(x) = \frac{x-a}{b-a} , a \leq X \leq b](https://tex.z-dn.net/?f=%20F%28x%29%20%3D%20%5Cfrac%7Bx-a%7D%7Bb-a%7D%20%2C%20a%20%5Cleq%20X%20%5Cleq%20b)
And for this case we can write the probability like this:
![P(X](https://tex.z-dn.net/?f=%20P%28X%3C3.7%29%3D%20F%283.7%29%20%3D%20%5Cfrac%7B3.7-3.5%7D%7B3.8-3.5%7D%20%3D0.667)
And then the final answer for this case would be ![\frac{2}{3}=0.667](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%3D0.667)
Step-by-step explanation:
For this case we define our random variable X "price of gasoline for a city in the USA" and we know the distribution is given by:
![X \sim Unif (a=3.5, b=3.8)](https://tex.z-dn.net/?f=%20X%20%5Csim%20Unif%20%28a%3D3.5%2C%20b%3D3.8%29)
And for this case the density function is given by:
![f(x) = \frac{x}{b-a}= \frac{x}{3.8-3.5}=, 3.5 \leq X \leq 3.8](https://tex.z-dn.net/?f=%20f%28x%29%20%3D%20%5Cfrac%7Bx%7D%7Bb-a%7D%3D%20%5Cfrac%7Bx%7D%7B3.8-3.5%7D%3D%2C%203.5%20%5Cleq%20X%20%5Cleq%203.8)
And we want to calculate the following probability:
![P(X](https://tex.z-dn.net/?f=%20P%28X%3C3.7%29)
And we can use the cumulative distribution function given by:
![F(x) = \frac{x-a}{b-a} , a \leq X \leq b](https://tex.z-dn.net/?f=%20F%28x%29%20%3D%20%5Cfrac%7Bx-a%7D%7Bb-a%7D%20%2C%20a%20%5Cleq%20X%20%5Cleq%20b)
And for this case we can write the probability like this:
![P(X](https://tex.z-dn.net/?f=%20P%28X%3C3.7%29%3D%20F%283.7%29%20%3D%20%5Cfrac%7B3.7-3.5%7D%7B3.8-3.5%7D%20%3D0.667)
And then the final answer for this case would be ![\frac{2}{3}=0.667](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%3D0.667)
