x = number of hours
want to find probability (P) x >= 13
x is N(14,1) transform to N(0,1) using z = (x - mean) / standard deviation so can look up probability using standard normal probability table.
P(x >= 13) = P( z > (13 - 14)/1) = P(z > -1) = 1 - P(z < -1) = 1 - 0.1587 = 0.8413
To convert that to percentage, multiply 100, to get 84.13%
Answer:
140/20

Find out how far Molly walks in 1 minute.
4/70 = 0.057 miles
In 100 minutes,
0.057x100 = 5.714 miles
Rounded to the nearest tenth, 5.7 miles.
Hope I helped :)
