Answer:
His average speed for the rest of the journey was of 48mph.
Step-by-step explanation:
We use the following relation to solve this question:
![v = \frac{d}{t}](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7Bd%7D%7Bt%7D)
In which v is the velocity, d is the distance and t is the time.
First 32 miles at an average speed of 64mph.
So the time for these 32 miles is:
![64 = \frac{32}{t}](https://tex.z-dn.net/?f=64%20%3D%20%5Cfrac%7B32%7D%7Bt%7D)
![64t = 32](https://tex.z-dn.net/?f=64t%20%3D%2032)
![t = \frac{32}{64}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B32%7D%7B64%7D)
![t = 0.5](https://tex.z-dn.net/?f=t%20%3D%200.5)
Rest of the trip:
200 - 32 = 168 miles in 4 - 0.5 = 3.5 hours. So the average speed is of:
![v = \frac{d}{t} = \frac{168}{3.5} = 48](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7Bd%7D%7Bt%7D%20%3D%20%5Cfrac%7B168%7D%7B3.5%7D%20%3D%2048)
His average speed for the rest of the journey was of 48mph.
Answer:
12*12= 144 + 81= 225. 255/15= 15. Yes, this is a right triangle. I do not understand the question itself, but I hope this will help
Step-by-step explanation:
The answer is c
let’s say he rents it for 2 hours,
t= hours, so t=2
20 is the deposit and since t is multiplied by 8,
8(2) + 20
Answer:
Step-by-step explanation:
the total cost for this question is $12.10.
let me know if this helped.
Answer:
10.05 meters
Step-by-step explanation:
If the diameter is 3.2 meters, then the radius is 1.6 meters.
Use the circumference formula, C = 2
r, and solve for C
C = 2
r
C = 2
(1.6)
C = 3.2![\pi](https://tex.z-dn.net/?f=%5Cpi)
C = 10.05
So, to the nearest hundredth of a meter, the circumference is 10.05 meters
