1 mile = 5,280 feet:
9 miles x 5280 feet per mile = 47,520 total feet per hour
1 hour = 3600 seconds.
Divide total feet by seconds per hour:
47,520 feet / 3600 seconds per hour = 13.2 feet per second.
Multiply feet per second by number of seconds for distance traveled:
13.2 feet per second x 15 seconds = 198 total feet.

Answer:
What are we supposed to find?
Answer:
The example is telling you to first add up each number then divide by the amount of numbers that are present in the set. There are four in this example.
Secondly the difference between each data point will differ from each number. Basically subtract the sum from each number. Which is 5 in this case. But if its negative flip it to a positive.
Then add up each absolute value and divide by 4 twice.
P = 540, the principal
R = 4.4% = 0.044, the rate, simple interest
A = 991.44, the current value
Let x = years that Sally has held the account
Then
P + PRx = A
or
540 + 540*0.044*x = 991.44
23.76x = 991.44 - 540 = 451.44
x = 451.44/23.76 = 19
Answer:
Sally has held the account for 19 years.
