A man can row a boat at 20 kmph in still water. If the speed of the stream is 6 kmph, what is the time taken to row a distance of 72 km downstream?
Answer/Solution
36/14 hours
Steps/Work
Speed downstream = 20 + 6 = 26 kmph.
Time required to cover 72 km downstream = d/s = 72/26
= 36/13 hours.
Answer:E
Time required to cover 72 km downstream = d/s = 72/26
= 36/13 hours.
Answer:E
