You can check this answer by just seeing if it fits the requirements, which it does. Making it the correct answer.

34.4 miles

Step-by-step explanation:

Mathematically;

z-score = x-mean/SD

from the question, we have mean as 29 and standard deviation as 3.6 with z-score as 1.5

So we need to find the z-score here

1.5 = x-29/3.6

3.6 * 1.5 = x-29

5.4 = x-29

x = 29 + 5.4

x = 34.4
