Question

A man can row 24km/hr in still water. It takes twice as long to travel any distance upstream as compared to the same distance downstream. Find the speed of the stream?

• A. 12
• B. 10
• C. 8
• D. 6

Answer 1

Answer:

C. 8

Since it takes twice as long in upstream, Net Speed in upstream = x Net Speed in Downstream = 2x Let the speed of stream be y 24 - y = x 24 +y = 2x 24 + y = 2( 24 - y) 24 + y = 48 - 2y 3y = 24 y = 8 Speed of stream = 8 kmph.
