The distance between two piers is S miles. Two boats started moving simultaneously at speeds R1 and R2. How can you find the distance D between them if they moved for T hours in opposite directions.

distance = speed * time
their combined speed is R1+R2
So, D = S + (R1+R2)*T if they are moving away from each other.
So, what if they are approaching each other?
