r = d/t. Since r is on the right side of the equation, switch the sides so it is on the left side of the equation. rt=d. Divide each term by t and simplify.
d=rt
here we have to solve for r
in order to solve for r , we need to isolate r on the right side
on the right , r and t are in multiplication, so to eliminate t from right side, we will divide both sides by t
d/t =rt/t
so r=d/t
