For a car traveling 30 mph in normal conditions, the distance required to brake to a stop is normally with a mean of 50 feet and a standard deviation of 8. you are traveling in a area at 30 mph and a car swerves into your path at a distance of 60 feet away. what is the probability that you will be able to brake to a stop in less than 60 feet?

60 = 50+10
so, it is 10/8 = 1.25 above the mean
Check you Z table to find P(Z<1.25)
