Answer: $V=51\ \frac{mi}{h}$

Step-by-step explanation:

You need to used the following formula:

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

Where "V" is the speed, "d" is the distance and "t" is the time.

In this case you know that Kevin traveled at a constant speed on the highway from Hickory Hills to Chicago in 20 minutes (which is $\frac{1}{3}\ h$ ) and the distance is 17 miles. Then, you can identify that:

$t=\frac{1}{3}\ h\\\\d=17\ mi$

Therefore, knowing these values, you can substitute them into the formula. Then, you get:

$V=\frac{17\ mi}{\frac{1}{3}\ h}\\\\V=51\ \frac{mi}{h}$

poizon [28]

4323x - 78487 = 5693

4323x = 5693 - 78487

4323x = -72794

x = -72794/4323

x = -16.8387694

tresset_1 [31]

Answer:

The answer is 121

Step-by-step explanation:

So basically it's like dividing 4 from 4 and you get 1

Then 8 from 4 and it would come out as 2

And divide 4 once more from 4 and get 1 again

4÷4=1

8÷4=2

4÷4=1

Then out the answers together and you got 121
