what is the equation for speed (please help)

Do you mean terminal velocity?

When you're given what?

MEh I hate phyics but here you go
v stands for velocity
u is initial speed
2 is 2
a is acceleration
s is distance

v²=u²+2as

veloctiy = speeds right? (because I am unsure, there ia something about velocity having a magnitude and a direction or some (rap like that! )
