Answer:

50m

Step-by-step explanation:

speed (m/s2) = distance (m) ÷ time (s)

distance = speed (m/s2) x time (s)

1x20 =20m.

30s = 30m because they do 1 meter per second (every second)

50m in total if not counting the constant for half a hour.

<span>V=f(w)
</span><span>2w^3 + w^2 + 5w
</span><span>v=w^2*l
</span><span>svl l=v/w^2
