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.
Robins basket is heavier.
Teds basket: 5x7.25=36.25
Robins basket: 6x6.25=37.5
37.5-36.25= 1.25
It is heavier by 1.25 ounces or 1 and 1/4 ounces
I’m pretty sure it’s true. :)
One full turn is 360 so the equation would be 360/ 30= 12
