A person can row a boat 5 km an hour in still water. It takes him thrice as long to row upstream as to row downstream. Find the rate at which the stream is flowing.

Dear Student,

Speed of rowing by a person =5 km/hr.Let  Speed of stream =x km/hr Upstream Speed  =(5x) km/hr Downstream speed =(5+x) km/hr According to the question, 35x=5+x  5+x=153x  4x=10  x=2.5 km/hrhence speed of stream =2.5 km/hr

Regards
