The EPA inspector's speed was: 7.243 mph. Let x be the speed of the EPA inspector. Time taken by EPA inspector on his pedaling forward = 10/(x-3). Time taken by EPA inspector on his pedaling reverse = 10/(x+3). This time is equal to time taken by the column of trucks to move only 10 miles, when EPA inspector reaches rear of column he realizes that is where front was when he started his search, which is 10/3. So, 10/3 = 10/(x-3) + 10/(x+3) we get, x^2-6x-9=0. Solving for this quadratic equation we get x=7.243 mph.
