Answer:
45.712
Step-by-step explanation:
We need to find the Zscore of the area of 15 percent of the distribution ; using a Z table or calculator ;
Zscore of 15% of the distribution is : - 1.036
Using the Zscore formula :
Zscore = (x - mean) / standard deviation
Where, x = score
-1.036 = (x - 54) / 8
Cross multiply
-1.036 * 8 = x - 54
-1.288 = x - 54
x = - 8.288 + 54
x = 45.712

I'm going to assume the question said that she "couldn't" repair the tire and was forced to walk back home, that makes more sense.
With that in mind:
She rode her bike 2 miles.
She walked 4 miles on the way there, and 6 miles on the way back.
You can deduce that it was a 6 mile walk back because of the 2 mile bike ride, then the 4 mile walk that it took to get there.
All in all that rounds out to 10 mile walking, and 2 mile biking. That is 8 miles more walking than biking.
