Distance to travel = 20 m.
Let us determine the time, t, that each participant took to complete 20 m.
Barbara:
Average speed = (3 m)/(2 s) = 1.5 m/s
t = 20/1.5 = 13.3 s
Mark:
t = 5 s
Carlos:
y = x + 1
where
y = 20 m
x = time, t
Therefore
t =x = y - 1 = 20 - 1 = 19 s
Summary:
Barbara: 13.3 s
Mark: 5 s
Carlos: 19 s
Answer:
The winner is Mark

Answer:
A) 0.38
Step-by-step explanation:
By SOH CAH TOA, the <em>sine of an angle is its opposite side divided by the hypotenuse</em>.
<em>The opposite of ∠C is 5, and the hypotenuse is 13</em>.
So, sin(C) = 5/13 ≈ 0.38.
