Lets do some math in the meantime.
A F-22 can travel at a speed of 1,498 mph. it's cruising speed is 1,220 mph. An F-15 can travel at a top speed of 1,650 mph, with a cruising speed of about 570 mph.
There are about 60 minutes in an hour. So that's about 24.9 miles per minute, 20.3 miles per minute for the F22, and 27.5 miles per minute and 9.5 miles per minute.
There are about 60 seconds in a minute. That's 0.41 mps at max speed for the F22, and .46 mph for the F15.
For both jets, they take all of two seconds to escape the radius of the blast while fleeing the area. Considering it takes Starscream a second or two to notice it, he can escape the area in less than five seconds (provided he doesn't have to change direction too much, and he's already at that speed). And that's using those jets as a reference to his older forms (Movie and G1). I'm assuming he has a similarly capable form in Fall of Cybertron/War for Cybertron.
I'm not good at math, and most of this was done through google, so sue me.
