Question

A boat goes upstream at 36 km/h and downstream at 40 km/h. The distance covered in each trip being the same, find the speed of boat in still water.

• A. 45 km/h
• B. 34 km/h
• C. 38 km/h
• D. 2 km/h

Answer 1

Answer:

C. 38 km/h

if we know the upstream and downstream speed then the speed in still water is the mean of these two speeds $=\frac{36+40}{2}=38kmph$
