That's pretty quick for your age. Not as fast as the 7:26 someone I know did at about the same age but then he used to be a pro runner and one of only a handful of Scots that have done an official sub 4 min mile....
For people that have not done the 1.5 mile but have done other distances, you can use this calculator which does a real good job of estimating different times for diff distances. All you need is an actual time for an actual distance - http://www.mcmillanrunning.com/mcmillanrunningcalculator.htm
I put in various actual times for various distances I have done and its pretty spot on for the others so works well...
Put in a few of my recent PB's which suggest I should be a lot quicker over the 1-2mile distances - I'd better pull my fiinger out
