If you run for 0.4 hours at 7 mph, how fast should you walk during the next 0.8 hours to have the average speed of 5 mph?

Orlov [11]

4mph

0.4 x 7 mph =2.8 miles - distance run.

Let the required speed =S

[2.8 + 0.8S] / [0.4+0.8] =5, solve for S

S =4 mph - must walk to attain an average of 5 mph, or:

6 miles / 1.2 hours =5 mph

What is the equation of the line that passes through the point (-6, 4) and has a slope of -5/6

tangare [24]

Answer:

$y = -\frac{5}{6}x -1$

Step-by-step explanation:

So, we know the slope is -5/6. From here we can write this equation:

$y = -\frac{5}{6}x + b$

In the question they give us both the x and y in this equation (-6,4)

Plug them in to the equation and solve for b:

$4 = -\frac{5}{6} (-6) + b\\4 = \frac{30}{6} + b\\4 = 5 + b \\-1 = b$

Now, we can write the equation as follows:

$y = -\frac{5}{6}x -1$

I hope this helps!!
