Alicia wanted to lose some weight, so she planned a day of exercising. She spent a total of 3 hours riding her bike and jogging.

hram777 [196]

Using the relation between velocity, distance and time, it is found that her jogging rate was of 6 mph.

<h3>What is the relation between velocity, distance and time?</h3>

Velocity is <u>distance divided by time,</u> hence:

$v = \frac{d}{t}$

Jogging, her velocity was of v, while the time was of t, for a distance of 12 miles, hence:

$v = \frac{12}{t}$

Biking, her velocity was of v + 6, while the time was of 3 - t, for a distance of 12 miles, hence:

$v + 6 = \frac{12}{3 - t}$

$v = \frac{12}{3 - t} - 6$

Then:

$\frac{12}{t} = \frac{12}{3 - t} - 6$

$\frac{12}{3 - t} - \frac{12}{t} = 6$

$\frac{12t - 36 + 12t}{t(3 - t)} = 6$

18t - 6t² = 24t - 36

6t² + 6t - 36 = 0

t² + t - 6 = 0

(t + 3)(t - 2) = 0. -> t = 2 hours.

Hence her jogging rate in mph is given as follows:

$v = \frac{12}{2} = 6$

10x+2=32 <br> what does x stand for

Sever21 [200]

Answer: x = 3

First, subtract 2 from both sides of the equation to get 10x = 30.

Then divide both sides by 10 to isolate x and you get x = 3.

Hope this is helpful :)
