It will take Adam four hours to drive to Disney Park, and 2.5 times less time if driving 45 mph faster. What is the distance Ada

Mashcka [7]

<h2>Hello!</h2>

The answer is:

The distance to over by Adam to get to the park is 108 miles.

To solve the problem, we need to write two equations using he given information about the times and his speed.

So,

For the first equation we have: Travel to Disney Park

$time=4hours$

$Distance=v*4hours$

For the second equation we have: Travel back from Disnery Park

$time=4hours-2.5hours=1.5hours$

$Speed=v+45mph$

$Distance=(v+45mph)*1.5hours$

Then, if Adam covered the same distance going and coming back, we have:

$v*4hours=(v+45mph)*1.5hours$

$v*4hours=v*1.5hours+45mph*1.5hours$

$v*4hours-v*1.5hours=45mph*1.5hours$

$v*2.5hours=67.5miles$

$v=\frac{67.5miles}{2.5hours}=27\frac{miles}{hour}=27mph$

We have that the speed when he was going to Disney Park was 27 mph.

Now, to calculate the distance, we need to substitute the obtained speed in any of the two first equations.

Therefore, substituting the speed into the second equation, we have:

$Distance=(v+45mph)*1.5hours$

$Distance=(27mph+45mph)*1.5hours=72mph*1.5hours=108miles$

Hence, we have that the distance that Adam should cover to get to the park is 108 miles.

Havea nice day!

When downloading a large file from the internet Alice interrupted the download by closing her computer. Later that evening she r

Temka [501]

Using the slope concept, it is found that the rate of download of the file is of 1920 MB/s.

<h3>What is the slope?</h3>

The slope of a linear function is given by the <u>change in the output divided by the change in the input</u>.

In this problem:

3 minutes since resuming the download 6720 total MegaBytes (MB).

5 minutes since resuming the download 10560 total MegaBytes (MB) of the file had been downloaded..

Hence, in 2 minutes, there was a change of 10560 - 6720 = 3840 MB, which means that the slope is:

$m = \frac{3840}{2} = 1920$

The rate of download of the file is of 1920 MB/s.

Write y+1=5/2(x-2)+2 in standard form step by step please

Elden [556K]

Answer: 5x - 2y = 8

y+1=5/2(x-2)+2

multiply the each side by 2 to get rid of the fraction

2 (y+1) = (5/2 (x-2) +2 )2

2y+2=5(x-2)+4

now distribute the 5

2y+2=5x-10+4

subtract the two from each side

2y=5x-10+4-2

add like terms

2y=5x-8

subtract 5x from each side

2y-5x=-8

multiple the whole equation by -1 to make the 5x a positive

-2y+5x=8

hope this helps!
