While solving for the variable t in the literal equation d=rt,
is used as the inverse operation to isolate the variable t.
To isolate the variable t in the literal equation d=rt, we need to divide both sides by r. This is because multiplication by r is the opposite (or inverse) operation of division by r. Dividing both sides by r gives:
d/r = t
Therefore, the variable t is isolated on one side of the equation and we have solved for t.
