I HAVE SOLVED FRST QUESON PLEASE SOLVE SECOND WTH

a-)A radar unit is used to measure speeds of cars on a specific motorway. The speeds are normally distributed with a mean of 90 km/hr and a standard deviation of 10 km/hr. What is the probability that a car picked at random is traveling at more than 100 km/hr?

b-)In another motorway, the speeds are normally distributed with standard deviation of 20 km/hr, and 0.3085 of the cars are traveling at a speed of less than 70 km/hr. What is the mean of the speed of cars traveling on this motorway.
