Determine the speed of the stream and that of the boat in still water. Let the speed of boat in still water be x km/hr & let the speed of stream be y Missing: vba.

Let us start by recalling some of the formulas for this section. Suppose the speed of a certain boat in still water is �u� km/hr and the speed of the stream is �v� km/hr, then: Speed of this boat downstream = (u + v) km/hr. Speed of this boat upstream = (u -v) km/hr. Also, if the downstream speed is �a� km/hr (suppose) and the speed upstream is b km/hr, then:Missing: vba.
