Answer:
362.02
Step-by-step explanation:
First, find the mean. You'll need it to compute the variance.

The variance of the sample is then computed with the formula

The standard deviation is the square root of the variance, so
-x+3x=2x
2x=2+6
2x=8
8/2=4
x=4
Answer:
61.7295 (61.7) miles
If I'm reading this correctly, this is just a simple addition equation. You'd add up 23.4865 and 38.243 to get 61.7295 miles, or 61.7 miles.
Hope I helped! ☺
