  1. The speed of a boat in still water is 2km/hr. If its speed upstream be 1 km/hr, then speed of the stream is ?
    1. 1.5 km/hr
    2. 3 km/hr
    3. 1 km/hr
    4. None of these
Correct Option: C

Let the speed of stream be x km/hr
Then, speed upstream = (2 - x ) km/hr
⇒ 2 - x = 1
∴ x = 1 km/hr
