I know it may be too late, but maybe it will eventually help you or someone else. If a plane travels with a speed of 570 miles per hour for 7 hours, then he will travel 570 * 7 = 3990 miles in that time.

Answer:
A = 2,384.1708
Step-by-step explanation:
A = P(1 + rt)
P = 942.36
r = 12.75%
t = 12 months
A = 942.36(1 + 12.75/100(12))
A = 942.36(2.53)
A = 2,384.1708
The answer is 4 Because 0.5 times 4 is 2
This is the "empirical rule." Approx. 68% of a data set lie within one standard deviation of the mean.
