Pretend you are in a boat or plane in still water/air and traveling x miles per hour. If you face into a current, your rate would be x - c ( where c is the speed of the current), because the current slows you down. If you turn with the current, so the current makes you move faster, then your new rate is x + c. Here we look at word problems that combine this current idea with the relationship that distance = rate times time.
