Answer:
286
Step-by-step explanation:
Answer:
![V = \frac{182.4 mi}{3 hr}= 60.8 \frac{mi}{hr}](https://tex.z-dn.net/?f=%20V%20%3D%20%5Cfrac%7B182.4%20mi%7D%7B3%20hr%7D%3D%2060.8%20%5Cfrac%7Bmi%7D%7Bhr%7D)
And then we can find the distance travelled in 11 hours with this formula:
![D = Vt](https://tex.z-dn.net/?f=%20D%20%3D%20Vt)
And replacing we got:
![D = 60.8 \frac{mi}{hr} *11 hr =668.8 mi](https://tex.z-dn.net/?f=%20D%20%3D%2060.8%20%5Cfrac%7Bmi%7D%7Bhr%7D%20%2A11%20hr%20%3D668.8%20mi)
So then after 11 hours she will travel 668.8 mi
Step-by-step explanation:
For this case w eknow that Alicia drove at a constant speed 182.4 mi in 3 hours. We can find the speed with this formula:
![V= \frac{D}{t}](https://tex.z-dn.net/?f=%20V%3D%20%5Cfrac%7BD%7D%7Bt%7D)
Where V is the velocity, D the distance and t the time if we replace we got:
![V = \frac{182.4 mi}{3 hr}= 60.8 \frac{mi}{hr}](https://tex.z-dn.net/?f=%20V%20%3D%20%5Cfrac%7B182.4%20mi%7D%7B3%20hr%7D%3D%2060.8%20%5Cfrac%7Bmi%7D%7Bhr%7D)
And then we can find the distance travelled in 11 hours with this formula:
![D = Vt](https://tex.z-dn.net/?f=%20D%20%3D%20Vt)
And replacing we got:
![D = 60.8 \frac{mi}{hr} *11 hr =668.8 mi](https://tex.z-dn.net/?f=%20D%20%3D%2060.8%20%5Cfrac%7Bmi%7D%7Bhr%7D%20%2A11%20hr%20%3D668.8%20mi)
So then after 11 hours she will travel 668.8 mi
Answer:
115
Step-by-step explanation:
2 1/2 x 5 3/4 x 8 = 115
you just need to multiply them all and that's it
Answer:
-12 feet per second
Step-by-step explanation:
average rate of change over [0.75, 1.25] = ![\frac{f(1.25) - f(0.75)}{1.25 - 0.75}](https://tex.z-dn.net/?f=%5Cfrac%7Bf%281.25%29%20-%20f%280.75%29%7D%7B1.25%20-%200.75%7D)
f(1.25) - f(0.75) = 4 - 10 = -6
1.25 - 0.75 = 0.5
=
= -12
