statistics/excel

I am in an applied stat class and I need help making a predictive line in excel or by hand, I am not sure how to get it to come out so that I can answer

"what is the expected age of a person who is caught driving 86 mph?"
data is b0=102.33 and i am not sure what b1=.
data set= age 32, 41, 18, 69, 60,
speed = 89, 78, 93,68,71, respectively.
I have found the mean and mode, variance of age, Sx of speed, z-score to find the percentage of drivers who are caught speeding that will drive faster than 75mph. I have also found the covar of age and speed, and have done a t-test of correlation, this is my last part and i have worked on it for days and I know that I am missing something simple. It is due tomorrow so any help is appreciated. Thanks
