D=st when s and t is subject of formula

If D, s, and t are related by the formula D=st, we can solve for either s or t as follows:

If we want to solve for s:

D=st
Divide both sides by t:
D/t = s
Therefore, s = D/t

If we want to solve for t:

D=st
Divide both sides by s:
D/s = t
Therefore, t = D/s
