Question 1143482
<br>
A solution using logical reasoning instead of formal algebra....<br>
He walked for 1.5 miles at a rate half of his jogging speed.<br>
If he had not tired and kept jogging instead, he could have covered 3 miles in the same amount of time.<br>
So in the 2 hours it took for the whole trip he could have covered 9+3=12 miles if he had continued jogging.<br>
That means his jogging speed is 12/2 = 6mph.
