(x + 5)*2 = (x � 5)*5/2 X = 45 kmph. Let x = speed in still water Let c = speed of the current The main difference with these problems is rate needs to be expressed using two variables because moving upstream the current is against you and downstream it moves with you. Distance Rate Time Upstream x?c Downstream x+c. Upstream speed = b ? c. Problem. The speed of a boat in still water is 30 mph.
