Rationale: Speed downstream = d/t = 85/(2 1/2) = 34 kmph
Speed upstream = d/t = 45/(2 1/2) = 18 kmph
The speed of the stream = (34 - 18)/2 = 8 kmph
The answer: (D)
Question: A man rows his boat 85 km downstream and 45 km upstream, taking 2 1/2 hours each time. Find the speed of the stream?

Rationale: 12
12 × 2 + 2 = 26
26 × 2 + 2 = 54
54 × 2 + 2 = 110
110 × 2 + 2 = 222
222 × 2 + 2 = 446
