A car travels for 3 hours and covers 156 miles. Find the average speed of the car.
lidiya [134]

Answer:

52 miles per hour

Step-by-step explanation:

Firstly, It is important to point out  that it is Average speed. The Average speed throughout all the way the car traveled.

And this is may calculated by a simple formula or if you'd rather by a proportion. Let's pick this simple formula, what's going to be useful.

Let's do the math!

Average speed = Δs/Δt

Δs = Variation of Space (given in miles) =156 -0

Δt =Variation of Time (given in hours) =3-0

Average Speed = 156-0/3-0 =156/3 =52 miles per hour

It is important to say, Average speed, is a rate so it is given in miles per hour

The area of a rectangle is 4y + 10.
galben [10]
By definition, the area of a rectangle is given by:
 A = (w) * (l)&#10;
 Where,
 w: width
 l: long
 We then have the following area:
 A = 4y + 10&#10;
 Factoring the area we have:
 A = 2 (2y + 5)&#10;
 Therefore, according to the definition, two possible dimensions of the rectangle are:
 w = 2&#10;&#10;l = 2y + 5
 Answer:
 
The area of the rectangle in factored form is:
 
A = 2 (2y + 5)&#10;
 One possible set of dimensions for this rectangle is:
 
w = 2&#10;&#10;l = 2y + 5
