let stream speed= x km/hr
upstream speed of boat=5-x km/hr
downstream speed of boat=5+x km/hr
15/(5-x)=22/(5+x)
15(5+x)=22(5-x)
75+15x=110-22x
37x=35
x=35/37=.945 km/hr
upstream speed of boat=5-x km/hr
downstream speed of boat=5+x km/hr
15/(5-x)=22/(5+x)
15(5+x)=22(5-x)
75+15x=110-22x
37x=35
x=35/37=.945 km/hr
