Answer:
3
Step-by-step explanation:
The common difference of an arithmetic sequence is the slope of the equation that describes it. The slope formula is useful in this case:
m = (y2 -y1)/(x2 -x1)
m = (219 -213)/(4 -2) = 6/2 = 3
The common difference of the corresponding arithmetic sequence is 3.
Time = distance

speed
= 7.2 x 10^2

1.2 x 10^3
= 0.6 hrs = 0.6 x 60 = 36 minutes.
Hope this helps!
Answer: heres an example
Step-by-step explanation:Convert the problem to an equation using the percentage formula: Y/X = P%
X is 60, Y is 12, so the equation is 12/60 = P%
Do the math: 12/60 = 0.20
Important! The result will always be in decimal form, not percentage form. You need to multiply the result by 100 to get the percentage.
Converting 0.20 to a percent: 0.20 * 100 = 20%
