The first step in solving this question is to split the journey into 2 parts. In the first part of the journey, miles are covered at a speed of 40 mph. In the second part the journey 5 miles are covered at a speed of 60 mph.
The equation to compute the time of a journey given the speed and distance is where
is the time,
is the speed and
is the distance.
The time for the first part of the journey is calculated as shown below,
.
The time for the second part of the journey is calculated as follows,
.
The total time is the sum of the times taken to cover each part of the journey and is calculated as shown below,
The time to cover the journey is a third of an hour or 20 minutes.
Answer:
The Area of the rectangle is 36
Step-by-step explanation:
One can use the vertices of the rectangle in coordinate form, by observing that (please see image attached):
(1) the distance between x-coordinates that share the same y-value give the length of the segments that define the horizontal sides of the rectangle,
(2) and the distance between y-coordinates that share the same x-value give the length of the segments that define the vertical sides of the rectangle,
Therefore, as an example of statement (1) above, the distance between the x-coordinates of : (-4,-3) and (-1,-3) which share the same "y-value" -3, is:
| -1 - (-4)| = |-1+4| = |3| = 3 which is the length of the horizontal side of the rectangle (the base of the rectangle).
As an example of statement (2), the distance between the y-coordinates of: ((-1,-3, and (-1,9) which share the same "x-value" -1, is:
| 9-(-3)| = |9+3|=|12|=12 which is the length of the vertical side of the rectangle (the height of the rectangle).
So, the area of the rectangle which is defined as the product of its base times its height, is given by:
