Answer:

The answer is " $\bold{\frac{9}{13}}$ "

Step-by-step explanation:

In this question, the image file is missing, which is defined in the attached file. please find it.

$\to raise= y_2-y_1$

$=-1-(-10)\\\\=-1+10\\\\=9$

$\to run= x_2-x_1$

$=9-(-4)\\\\=9+4\\\\=13$

$\to \text{formula for slope} =\frac{rise}{run} =\frac{9}{13}$

Jason jogged 2/3 mile in 1/3 hour. What was his speed in miles per hour?

fenix001 [56]

Answer:

I honestly was having the worst time trying to solve this sorry :(, for real idk if any of these are right

i got 2 answers; 1st: ≈0.5 mph

the 2nd; 2 mph

Step-by-step explanation:

Speed = $\frac{Distance}{Time}$

2/3 miles = 3520 feet

1/3 hours = 20 minutes

------Make a proportion-----

$\frac{3520ft}{20min} = \frac{1 mi=5280 ft}{1hr = 60min}$

cross multiply------

3520 * 60 = 211200

5280 * 20 = 105600

Divide $\frac{211200}{105600}= 2$

---(this is where i got confused cuz 2 doesn't make any sense)--

If you flip them, $\frac{105600}{211200}=0.5$ which makes more sense

hope i helped :(
