The time needed to run the second half of the race is 8.44 s
Step-by-step explanation:
The total distance covered by the athlete during the race is
d = 200 m
And the total time taken to cover this distance is
T = 19.19 s
We also know that the time the athlete needs to cover the first half of the race is
[tex]t_1 = 10.75 s[/tex]
Also, we know that
[tex]T=t_1 + t_2[/tex]
where [tex]t_2[/tex] is the time the athlete takes to cover the second half of the race.
Re-arranging this equation and susbtituting the values, we find the value of t2:
[tex]t_2 = T-t_1 = 19.19-10.75=8.44 s[/tex]
