Given the rationale, provide a reasonable question and answer. Step-by-step reasoning process: Speed downstream = d/t = 120/(4) = 30 kmph
Speed upstream = d/t = 92/(4) = 23 kmph
The speed of the stream = (30 - 23)/2 = 4 kmph
The question and answer:
A man rows his boat 120 km downstream and 92 km upstream, taking 4 hours each time. Find the speed of the stream?
Options:
(A) 6 kmph
(B) 4 kmph
(C) 2 kmph
(D) 8 kmph
(E) 1 kmph
The answer is (B)
