The speed at which a man can row a boat in still water is 25 kmph. If he rows downstream, where the speed of current is 11 kmph, what time will he take to cover 80 metres?
Select:
A) 18 seconds
B) 27 seconds
C) 26 seconds
D) 12 seconds
E) 8 seconds

Rationale: "speed of the boat downstream = 25 + 11 = 36 kmph = 36 * 5 / 18 = 10 m / s hence time taken to cover 80 m = 80 / 10 = 8 seconds . answer : e"
Answer: E
