Respuesta :
26.2/3.4 would be the average velocity for the run.
7.7 miles/hr
Answer:
[tex]\vec v = 3.6 mph[/tex]
Explanation:
As we know that the total path length of the Marathon is given as
[tex]L = 26.2 miles[/tex]
while the straight distance between start and finish lines is given as
[tex]d = 12.2 miles[/tex]
so here we can say that the displacement is the straight line distance between initial and final position which is 12.2 miles
so it is given as
[tex]\vec d = 12.2 miles[/tex]
now the average velocity is defined as the ratio of displacement and time
[tex]\vec v = \frac{\vec d}{time}[/tex]
[tex]\vec v = \frac{12.2 miles}{3.4 hr}[/tex]
[tex]\vec v = 3.6 mph[/tex]
