Yohan Blake ran the 100-meter race in the 2012 Olympics in 9.75 seconds. Compare the speeds if he ran the 200-meter race in 19.5 seconds.

The speeds are equal.

Step-by-step explanation:

100 meters in 9.75 seconds compared to 200 meters in 19.5 seconds.

(100 m)/(9.75 s) = 10.2564 m/s

(200 m)/(19.5 s) = 10.2564 m/s

The speeds are equal.

Sample Response: The unit rates for both races would be equal. So his speed would be the same for both race.

Step-by-step explanation:

hope this helps

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
