Going the Distance Achievement
Going the Distance5
Threw someone a long, long way
In order to throw someone, go up to them and hold to take them as a human shield and hit again to throw them. You must throw someone over 100 feet (33.3 meters) for this achievement.
The best way to do this is in the Crowd Control activity in the Hotels and Marina district. One of the maps for this activity is in an airport. When playing on the map, simply throw a fan onto the moving section of the giant ramp, and you should get credit for a throw of several hundred feet.
If you're having trouble with that method, you can always try throwing someone off a cliff or building. Several missions involve rooftops, and all you need to do is grab an enemy and throw him off.
