The concept of product mix is a group of products sold by a seller and purchased by a buyer. It includes all product lines and product items

Does size mean length? Is height, width and depth OK

Of course

What are the length, width and depth of the product mix

The length of product portfolio refers to the total number of product items in an enterprise's product portfolio. The width of product portfolio refers to the number of product categories in an enterprise. The depth of product portfolio refers to the number of varieties in each product category

The fastest motorcycle in the world, what's the speed of one kilometer per hour? How many meters per second?

The plane travels about several meters per minute

The speed of an aircraft is rarely expressed in a few meters per minute. It is usually expressed in the following ways: 1. In navigation calculation, the speed of an aircraft is generally expressed in knots (knots). Generally speaking, it flies 480-540 knots for general jet civil aircraft; 2. Generally speaking, it is expressed in kilometers per hour for ordinary people. Generally speaking, it is expressed in knots for general jet civil aircraft, About 850-900 km / h; 3: if expressed in terms of sound speed, the general jet civil aircraft is about 0.9 mach. When the aircraft is cruising in the stratosphere, the average speed is 780 km / h. about 780 / 3.6 = 216.666 M / s in one second; about 216 × 60 = 13000 M / MIT in one minute

How many kilometers an hour does a cyclist travel? How can a few meters per minute turn into thousands of meters per hour
There is another question. The ratio of money between Party A and Party B is 3:1. If Party A gives Party B 0.6 yuan, the ratio of money becomes 2:1. How much money do they have?
Tell me why

1.8 minutes 4 / 5m, one hour = (4 / 5) / 8 * 60 / 1000 = 0.006km/h
2. Let B have X Yuan and a have 3x yuan
Then 3x-0.6 = 2 * (x + 0.6)
The result is x = 1.8
So two people have a total of = 4x = 4 * 1.8 = 7.2 yuan

Xiao Ming and Xiao Liang walk from school to the library. It takes 10 minutes for Xiao Ming and 12 minutes for Xiao Liang. What is the simplest integer ratio of the time taken by Xiao Ming and Xiao Liang?

The simplest integer ratio of time used by Xiaoming and Xiaoliang is 5:6
10：12=5:6

Xiao Ming goes to school every day. After walking for 10 minutes, he runs for 2 minutes and just arrives at school. One day, he starts running after walking for 6 minutes, and the result is 2 minutes and 24 seconds earlier. How many times is his running speed? 9 it's better to use the 1-yuan equation, if you use 2 yuan,)

Suppose Xiao Ming's walking speed is x meters per second, and his running speed is y meters per second. He usually walks 10 minutes to school, 10 * 60 * x + runs 2 minutes, 2 * 60 * y. on this special day, he walks 6 minutes, 6 * 60 * x + (12 minutes, 12 * 60 - early time (2 * 60 + 24) - walks 6 * 60 * y

Xiao Ming goes to his classmate's home which is 9 kilometers away. It is known that his walking speed is 3 kilometers per hour. He has to rest for 10 minutes after every 50 minutes. If he wants to get to his classmate's home before 12:00 noon, when will he start in the morning at the latest?

9 / 3 = 3 (hours), because 3 × 60 / 50 = 3.6 (Times), so you need to rest 3 times to arrive, then the rest time is: 10 × 3 = 30 (minutes), 3 hours + 30 minutes = 3 hours and 30 minutes, 12:00-3:30 = 8:30. A: he will leave at 8:30 at the latest

Xiaoming's home is 5km away from his destination. It takes him 60 minutes to rest for 10 minutes. What's the average speed per hour?

6Km/h
