How long you would cook a 2.2 pound beef roast depends upon how you like it cooked. For a rare beef roast, cook at 200 degrees Celsius/390 degrees Fahrenheit for 30 minutes. For a medium beef roast, cook for 45 minutes or for well done meat, cook for an hour.

I have a 2.6 Kg 'silverside' of beef... How long should I roast it in the oven, and at what temperature? ...Reduce the heat to 190C/375F/Gas 5 and roast for half an hour per kilo for rare, adding another ten minutes per kilo for medium rare
When cooking Roast beef, its usually 20 minutes per pound at 350 degrees.
My sister-in-law taught me the perfect way to cook a roast beef. Preheat oven to 400, put roast in a pan with 1 cup of water, season with salt & pepper, and quarter one peeled onion and place around the roast. Cook for 1/2 hour, then reduce the temperature to 350 and cook for an hour. The first half hour at the higher heat, sears the meat and seals in the juices. The center will be medium rare and the outer edges will be medium well. Perfection! If you are so inclined, you can use the pan drippings to make gravy!
put roast in a preheated 500 degree oven for 20 minutes, then reduce heat to 325 and cook until done - use a meat thermometre and take roast out at 125 -135 and tent with foil for additional 20 minutes or so.
Medium Rare
In a moderate oven (180 deg. C) roast beef generally takes - per 500 grams: 20-25mins for rare, 25-30mins for medium and 30-35mins for well done. Using a meat thermometer (inserted in the thickest part away from fat or bone) look for 60 deg. for rare, 70 deg. for medium and 75 deg. for well done. (all temps. Centigrade).
I would cook it at 350 for 30 minutes covered. Then, uncover and cook until desired done-ness. I like medium rare which is generally achieved in an additional 15-30 minutes. For more tender meat you can cook at a lower temperature for a longer time.
This depends on how you want the finished roast, rare, med rare or well done. An hour at 350 degrees for rare, an hour and thirty for med rare and up to 3 hours for well done.
