1.	A person rowing at the rate of 5 km/h in still water, takes thrice as much time ingoing 40 km upstream as in going 40 km downstream. Find the speed of the stream.
Answer» Consider, SPEED of rowing by a person =5 km/hr. Speed of STREAM =X km/hr Upstream Speed =(5−x) km/hr Downstream speed =(5+x) km/hr According to the QUESTION, ⇒ 5−x 40 = 5+x 3×40 ⇒5+x=15−3x ⇒4x=10 ⇒x=2.5 km/hr Hope U satisfied babe pls follow me

Speed of STREAM =X km/hr

Upstream Speed =(5−x) km/hr

Downstream speed =(5+x) km/hr

According to the QUESTION,

⇒

5−x

5+x

3×40

⇒5+x=15−3x

⇒4x=10

⇒x=2.5 km/hr
