A rower can row upstream at 22 kph and downstream at 34 kph. What is the speed of the rower in still water?
Options: A) 28 B) 29 C) 30 D) 31 E) 32
Let V be the rower's speed in still water.   Let S be the speed of the current in the stream   V-S = 22   V+S = 34   When we add the two equations, we get: 2V = 56   Then V = 28 kph.   The answer is 28.
