Question

A boat goes at 16 kmph along the stream and kmph against the stream. The speed of the boat (in kmph) in still water is :10

• A. 12 kmph
• B. 11 kmph
• C. 13 kmph
• D. 8 kmph

Answer 1

Answer:

C. 13 kmph

Given:

Rate of Downstream = 16 kmph

Rate of Upstream = 10 kmph

calculation:

Speed of boat in still water = $\frac{1}{2}$(rate downstream + rate upstream)

$=\frac{1}{2}(16 + 10) = 13 kmph.$
