Answer:
Step-by-step explanation:
jason ran the first 3 miles at 8mil/hr ie; so it took him 3/8 hrs to run 3 miles.
jason ran the final 2 miles at 6mil/hr ie; it took him 2/6 hrs to run 2 miles
the total time he took to run 5 miles will then be; [tex]\frac{3}8} +\frac{2}{6} = \frac{17}{24}hrs[/tex]
if we divide distance/time we get his speed/velocity;
ie, 5/(17/24) = 6.47mil/hr
