On a dark and stormy night Snoopy suddenly saw a flash of lightning. Ten seconds later he heard the sound of thunder. The speed of sound is $1088$ feet per second and one mile is $5280$ feet. Estimate, to the nearest half-mile, how far Snoopy was from the flash of lightning. If the answer is $x$ miles, what is the value of $x$?

Let's think step by step and output the final answer within \boxed{}.
