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:
Step-by-step explanation:
4A Area is 40. The area is the length times the width giving you an answer of 40 sq in.
4A Perimeter is is 2L+2W. Multiply the length by 2 then the width by two and add them together this gives you 8+20 which is 28 inches.

Step-by-step explanation:
The length, width and height of the rectangular prism is ∛10
<h3>How to determine the dimensions?</h3>
The volume is given as:
Volume, V = 10m^3
For a minimised volume, we have:
Length = Width = Height
This means that:
V = L^3
So, we have:
L^3 = 10
Take the cube root of both sides
L = ∛10
Hence, the length, width and height of the rectangular prism is ∛10
