Step-by-step explanation:
In order to describe speed of an object, we must describe the average speed of the entire trip. It is equal to the distance moved divided by time taken.
If a person covers a distance of 1 km to the library in 15 minutes, we can find its average speed.
Firstly, we convert 15 minutes to hour, 15 min = 0.25 hours
Now, using formula of speed = distance/time

It means that the average speed of the person is 4 km/h. Hence, the given statement is true.
Hello, the answer is simple it is W=6
Answer:

The quadratic equation has one real root with a multiplicity of 2.
Step-by-step explanation:
Given a quadratic equation:

You can find the Discriminant with this formula:

<em> </em>In this case you have the following quadratic equation:

Where:

Therefore, when you substitute these values into the formula, you get that the discriminant is this:
Since
, the quadratic equation has one real root with a multiplicity of 2 .
the answer will be 1255.725
87 is a whole number and is the larger one so your answer is going to be 87 something. Decimals are always based on 100% so 25 x 4 = 100 as well as 24 x 4 is 96. This make it 87 and 96/100. In decimal form, The number would look like this : 87.96
