The answer would be 3mph because 3/4 / 1/4 = 3. So the answer would be 3mph.

Answer:

His speed in miles per hour is:

<u>3Mph</u>

Step-by-step explanation:

Depending on the speed you take in miles per minute when passing it to miles per hour, you should consider the time it takes you to travel a mile.

Now: If 3/4 of a mile is 0.75 miles.

And it takes 15 minutes, so how long does it take 1 mile?

It is a rule of three.

0.75 miles = 15 minutes

1 mile = X

Clearing X would give :

 X = 15 * 1 / 0.75

X = 20 minutes takes a mile to travel

Now if it goes to 1Mpm how much is in Mph?

If it takes 20 minutes to travel 1 mile, how many travels in 60 minutes (1 hour)

Again rule of 3.

20 minutes = 1 mile

60 minutes = X

Clearing X would give:

X = 60/20

<u>X = 3 miles per hour.</u>

<u>Luis rides 3 miles per hour.</u>

What is the equation of the line with slope of ½ , and which passes through the point
Law Incorporation [45]

Answer:

y = 1/2x - 7

Step-by-step explanation:

slope intercept form:

y = mx + b

y = -5

m(slope) = 1/2

x = 4

y = mx + b

<em>substitute </em>

-5 = 1/2*4 + b

-5 = 2 + b

-5 - 2 = b

-7 = b

y = 1/2x - 7

What is the standard form of the ordered pairs, (2,0) and (0,-6)
maxonik [38]

Hello!

Explanation:

Slope-intercept form: → y=mx+b

m: represents the slope and is constant.

b: represents the y-intercept.

You had to used their rise/run.

\frac{rise}{run}

rise=y^2-y^1

run=x^2-x^1

x^1,y^1=(2,0)

x^2,y^2=(0,-6)

rise=y^2-y^1=-6-0=-6

run=x^2-x^1=0-2=-2

-6/-2=3

<u><em>So, therefore the slope is 3.</em></u>

Hope this helps!
