The mean or average speed of a mobile moving north is: <u>Vprom= 20.575 m/sec</u>
The average speed of a series of given speed values is calculated by <u>summing</u> each of the <u>speeds</u> and then <u>dividing</u> by the number of speeds , as follows:
Speeds:
V1=18.5m/s
V2=22m/s
V3=20.3m/s
V4=21.5m/s
V avg =?
Average V = ( V1+V2+V3 +V4)/4
Vavg = (18.5m/s + 22m/s +20.3m/s + 21.5m/s)/4
Vavg = 20.575nm/sec

Answer:
Sorry the screenshot is black but i would like to help if you can repost, it?
Step-by-step explanation:
let's use engineering notation for the sake of brevity.
1 trillion is 1,000,000,000,000, or just 1E12, twelve zeros.
1 million is then 1E6, six zeros.
we know the discharge for one day is 3E12 gallons, and that'd do just fine for country A for 5 months. How many gallons in 1 month only?
if there are 200million inhabitants in A, namely 200E6 or 2E8 inhabitants, how many gallons per inhabitant from all those 6E11 gallons?
Answer:
The correct option is C
C) Hungary
Step-by-step explanation:
Suppose we draw a vertical number line such that it shows elevations of different countries. For y=0, we get India. As all the rest of the values, expect Hungary, are given negative values, hence all the value will lie below India in the numbers line. The only country that lies above India in the number line is Hungary as only it has a positive number for the elevation. So the lowest elevation above 0 will be shown of Hungary which is 78.
