A boat rows upstream 25.3 km/hr and downstream 27.2 km/hr. The speed of the boat in still water will be:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 26.25 km/hr
Let u be the speed of the boat in still water and v the speed of the stream.
\( \displaystyle u-v=25.3 \)
\( \displaystyle u+v=27.2 \)
Adding the two equations:
\( \displaystyle 2u=52.5 \)
\( \displaystyle u=26.25\ \text{km/hr} \)
