"Emergency Please Help"!!!!!

A bus is scheduled to stop at a certain bus stop every 45 minutes. At the end of the day, buses still

stop after every 45 minutes, but because delays often occur earlier in the day, the bus is never early

and likely to be late. The director of the bus line claims that the length of time a bus is late is

uniformly distributed over the interval 0 to 35 minutes. If the director's claim is true, what is the

probability that the last bus on a given day will be more than 22 minutes late?

A) 0.78

B) 0.4

C) 0.37

D) 0.63
