It is about 65 blocks. If you bike you would go straight down 15th Ave NE. That road has a number of hills and the traffic is relatively fast. The bus is a good option. But then, a bus from anywhere in the city is a good option. If you are busing, there are more dynamic places I'd like to live unless you are really into Northgate mall and surrounding strip malls which is the main source of nearby retail.
About 10 minutes taking Roosevelt by car. The 73 bus takes 26 minutes and biking takes about the same amount of time. If you use google maps you can drag your cursor to revise your bike route and get different commute times.
A great tool I use to figure out the answer to questions like yours is Mapquest and GoogleMaps. You can put in address, ask directions and get turn by turn help to get where you want to go complete with distances.
