Lara jogs 1/5 kilometer to 1/6 hour. What is Lara rate in kilometer per hour? Write you answer in decimal form.
Natasha_Volkova [10]

Answer: 1.2\ kmph

Step-by-step explanation:

Given

Lara jogs \frac{1}{5} km in \frac{1}{6} hours

We know,

\text{distance=speed}\times \text{time}

\therefore \text{Rate of lara is }=\dfrac{\dfrac{1}{5}}{\dfrac{1}{6}}\\\\\Rightarrow \text{Rate=}\dfrac{6}{5}\\\\\Rightarrow \text{Rate=}1.2\ kmph

Can I get some help? I will be giving brainliest!
vfiekz [6]

Answer:

1.) slope = 2

2.) slope = -2\frac{2}{3}

3.) slope = \frac{2}{3}

4.) slope = \frac{1}{4}

5.) slope = 1\frac{8}{9}

6.) slope = -2

7.) slope = -3

Step-by-step explanation:

In order to find the slope we have to divide they "y" value (the number of units by which the piece of antler goes up) by the "x" value the number of units by which the piece of antler goes to the side). Notice the if the antler moves to the left as it foes up then the "x" value is negative.

Now as I said before we know this......

Let "m" be the slope, then....

m = \frac{y}{x}

So now we just have to plug in the y and x values for each antler and we will get the slopes for each one of them.

1.)

m = \frac{y}{x}

m= \frac{4}{2}

m = 2

2.)

m = \frac{y}{x}

m = \frac{4}{-1.5}

m = -2\frac{2}{3}

3.)

m = \frac{y}{x}

m = \frac{2}{3}

4.)

m = \frac{y}{x}

m = \frac{1}{4}

5.)

m = \frac{y}{x}

m = \frac{8.5}{4.5}

m = 1\frac{8}{9}

6.)

m = \frac{y}{x}

m = \frac{2}{-1}

m= -2

7.)

m = \frac{y}{x}

m = \frac{3}{-1}

m = -3
