Answer:
If you want a simple average, you can add all the speeds you see and divide them by the number of how many they are.
So firstly you have to calculate the speed of the first point, which is:
20 miles/0.5 hour
That means: 40 miles/hour
That would be your first "speed"
Then you calculate all of them :speed1+speed2+speed3 = something.
As an example: 20miles/hr + 40miles/hr+0miles/hr = 60miles/hr
Then, you divide it by how many "speeds" they are: 60miles/hr divided by 3 if I continue my previous example.
It is my first answer, and I hope I could help you a bit!
Sorry for the awkward English, as it is not my mother tongue.

Answer:
6
Step-by-step explanation:
3(x+2)=24
3x+6=24
-6 -6
<u>3x=18</u>
3
x=6
Try this:
8% of 2570 is 2570*0.08=205.6 units
and since the number of units were increasing every month you can multiply that by seven giving you 1439.2, then you can subtract that by your final amount of sales giving you the initial amount of 1130.8 units.
Range is the largest number minus the smallest.
210 - 68 = 142
142 is the range.
