Solution

The correct option is A (19 - x)
Let the speed of the stream be x km/hr.

Speed of boat in still water = 19 km/hr.

Upstream speed of boat = Speed of boat in still water - speed of the stream

So, Upstream speed of boat = (19-x) km/hr.

The correct option is A (19 - x) Let the speed of the stream be x km/hr. Speed of boat in still water = 19 km/hr. Upstream speed of boat = Speed of boat in still water - speed of the stream So, Upstream speed of boat = (19-x) km/hr.

The correct option is A (19 - x)
Let the speed of the stream be x km/hr.

Speed of boat in still water = 19 km/hr.

Upstream speed of boat = Speed of boat in still water - speed of the stream

So, Upstream speed of boat = (19-x) km/hr.
